xfs: compute the maximum height of the rmap btree when reflink enabled

xfs: rename m_ag_maxlevels to m_allocbt_maxlevels
Years ago when XFS was thought to be much more simple, we introduced m_ag_maxlevels to specify the maximum btree height of per-AG btrees for a given filesystem mount. Then we observed that inode btrees don't actually have the same height and split that off; and now we have rmap and refcount btrees with much different geometries and separate maxlevels variables.
The 'ag' part of the name doesn't make much sense anymore, so rename this to m_alloc_maxlevels to reinforce that this is the maximum height of the *free space* btrees. This sets us up for the next patch, which will add a variable to track the maximum height of all AG btrees.
(Also take the opportunity to improve adjacent comments and fix minor style problems.)

xfs: fix off-by-one in inode alloc block reservation calculation
The inode chunk allocation transaction reserves inobt_maxlevels-1 blocks to accommodate a full split of the inode btree. A full split requires an allocation for every existing level and a new root block, which means inobt_maxlevels is the worst case block requirement for a transaction that inserts to the inobt. This can lead to a transaction block reservation overrun when tmpfile creation allocates an inode chunk and expands the inobt to its maximum depth. This problem has been observed in conjunction with overlayfs, which makes frequent use of tmpfiles internally.
The existing reservation code goes back as far as the Linux git repo history (v2.6.12). It was likely never observed as a problem because the traditional file/directory creation transactions also include worst case block reservation for directory modifications, which most likely is able to make up for a single block deficiency in the inode allocation portion of the calculation. tmpfile support is relatively more recent (v3.15), less heavily used, and only includes the inode allocation block reservation as tmpfiles aren't linked into the directory tree on creation.
Fix up the inode alloc block reservation macro and a couple of the block allocator minleft parameters that enforce an allocation to leave enough free blocks in the AG for a full inobt split.

xfs: fix inode allocation block res calculation precedence
The block reservation calculation for inode allocation is supposed to consist of the blocks required for the inode chunk plus (maxlevels-1) of the inode btree multiplied by the number of inode btrees in the fs (2 when finobt is enabled, 1 otherwise).
Instead, the macro returns (ialloc_blocks + 2) due to a precedence error in the calculation logic. This leads to block reservation overruns via generic/531 on small block filesystems with finobt enabled. Add braces to fix the calculation and reserve the appropriate number of blocks.

Remove the verbose license text from XFS files and replace them with SPDX tags. This does not change the license of any of the code, merely refers to the common, up-to-date license files in LICENSES/
This change was mostly scripted. fs/xfs/Makefile and fs/xfs/libxfs/xfs_fs.h were modified by hand, the rest were detected and modified by the following command:
for f in `git grep -l "GNU General" fs/xfs/` ; do echo $f cat $f | awk -f hdr.awk > $f.new mv -f $f.new $f done
And the hdr.awk script that did the modification (including detecting the difference between GPL-2.0 and GPL-2.0+ licenses) is as follows:
$ cat hdr.awk BEGIN { hdr = 1.0 tag = "GPL-2.0" str = "" }
/^ \* This program is free software/ { hdr = 2.0; next }

xfs: reserve enough blocks to handle btree splits when remapping
In xfs_reflink_end_cow, we erroneously reserve only enough blocks to handle adding 1 extent. This is problematic if we fragment free space, have to do CoW, and then have to perform multiple bmap btree expansions. Furthermore, the BUI recovery routine doesn't reserve /any/ blocks to handle btree splits, so log recovery fails after our first error causes the filesystem to go down.
Therefore, refactor the transaction block reservation macros until we have a macro that works for our deferred (re)mapping activities, and fix both problems by using that macro.
With 1k blocks we can hit this fairly often in g/187 if the scratch fs is big enough.

xfs: implement swapext for rmap filesystems
Implement swapext for filesystems that have reverse mapping. Back in the reflink patches, we augmented the bmap code with a 'REMAP' flag that updates only the bmbt and doesn't touch the allocator and implemented log redo items for those two operations. Now we can rewrite extent swapping as a (looong) series of remap operations.
This is far less efficient than the fork swapping method implemented in the past, so we only switch this on for rmap.

We no longer calculate the minimum freelist size from the on-disk AGF, so we don't need the macros used for this. That means the nested macros can be cleaned up, and turn this into an actual function so the logic is clear and concise. This will make it much easier to add support for the rmap btree when the time comes.
This also gets rid of the XFS_AG_MAXLEVELS macro used by these freelist macros as it is simply a wrapper around a single variable.

xfs: fix off-by-one in inode alloc block reservation calculation [ Upstream commit 657f101930bc6c5b41bd7d6c22565c4302a80d33 ] The inode chunk allocation transaction reserves inobt_m
xfs: fix off-by-one in inode alloc block reservation calculation [ Upstream commit 657f101930bc6c5b41bd7d6c22565c4302a80d33 ] The inode chunk allocation transaction reserves inobt_maxlevels-1 blocks to accommodate a full split of the inode btree. A full split requires an allocation for every existing level and a new root block, which means inobt_maxlevels is the worst case block requirement for a transaction that inserts to the inobt. This can lead to a transaction block reservation overrun when tmpfile creation allocates an inode chunk and expands the inobt to its maximum depth. This problem has been observed in conjunction with overlayfs, which makes frequent use of tmpfiles internally. The existing reservation code goes back as far as the Linux git repo history (v2.6.12). It was likely never observed as a problem because the traditional file/directory creation transactions also include worst case block reservation for directory modifications, which most likely is able to make up for a single block deficiency in the inode allocation portion of the calculation. tmpfile support is relatively more recent (v3.15), less heavily used, and only includes the inode allocation block reservation as tmpfiles aren't linked into the directory tree on creation. Fix up the inode alloc block reservation macro and a couple of the block allocator minleft parameters that enforce an allocation to leave enough free blocks in the AG for a full inobt split.

xfs: fix inode allocation block res calculation precedence [ Upstream commit b2a8864728683443f34a9fd33a2b78b860934cc1 ] The block reservation calculation for inode allocation is supposed to consist of the blocks required for the inode chunk plus (maxlevels-1) of the inode btree multiplied by the number of inode btrees in the fs (2 when finobt is enabled, 1 otherwise). Instead, the macro returns (ialloc_blocks + 2) due to a precedence error in the calculation logic. This leads to block reservation overruns via generic/531 on small block filesystems with finobt enabled. Add braces to fix the calculation and reserve the appropriate number of blocks.

xfs: reserve enough blocks to handle btree splits when remapping In xfs_reflink_end_cow, we erroneously reserve only enough blocks to handle adding 1 extent. This is problematic if we fragment free space, have to do CoW, and then have to perform multiple bmap btree expansions. Furthermore, the BUI recovery routine doesn't reserve /any/ blocks to handle btree splits, so log recovery fails after our first error causes the filesystem to go down. Therefore, refactor the transaction block reservation macros until we have a macro that works for our deferred (re)mapping activities, and fix both problems by using that macro. With 1k blocks we can hit this fairly often in g/187 if the scratch fs is big enough. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Christoph Hellwig <hch@lst.de>

xfs: implement swapext for rmap filesystems Implement swapext for filesystems that have reverse mapping. Back in the reflink patches, we augmented the bmap code with a 'REMAP' flag that updates only the bmbt and doesn't touch the allocator and implemented log redo items for those two operations. Now we can rewrite extent swapping as a (looong) series of remap operations. This is far less efficient than the fork swapping method implemented in the past, so we only switch this on for rmap.
