xfs: convert remaining mount flags to state flags
The remaining mount flags kept in m_flags are actually runtime state flags. These change dynamically, so they really should be updated atomically so we don't potentially lose an update due to racing modifications.
Convert these remaining flags to be stored in m_opstate and use atomic bitops to set and clear the flags. This also adds a couple of simple wrappers for common state checks - read only and shutdown.

xfs: replace dop_low with transaction flag
The dop_low field enables the low free space allocation mode when a previous allocation has detected difficulty allocating blocks. It has historically been part of the xfs_defer_ops structure, which means if enabled, it remains enabled across a set of transactions until the deferred operations have completed and the dfops is reset.
Now that the dfops is embedded in the transaction, we can save a bit more space by using a transaction flag rather than a standalone boolean. Drop the ->dop_low field and replace it with a transaction flag that is set at the same points, carried across rolling transactions and cleared on completion of deferred operations. This essentially emulates the behavior of ->dop_low and so should not change behavior.

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: remove filestream item xfs_inode reference
The filestreams allocator stores an xfs_fstrm_item structure in the MRU to cache inode number to agno mappings for a particular length of time. Each xfs_fstrm_item contains the internal MRU structure, an inode pointer and agno value.
The inode pointer stored in the xfs_fstrm_item is not referenced, however, which means the inode itself can be removed and reclaimed before the MRU item is freed. If this occurs, xfs_fstrm_free_func() can access freed or unrelated memory through xfs_fstrm_item->ip and crash.
The obvious solution is to grab an inode reference for xfs_fstrm_item. The filestream mechanism only actually uses the inode pointer as a means to access the xfs_mount, however. Rather than add unnecessary complexity, simplify the implementation to store an xfs_mount pointer in struct xfs_mru_cache, and pass it to the free callback. This also requires updates to the tracepoint class to provide the associated data via parameters rather than the inode and a minor hack to peek at the MRU key to establish the inode number at free time.
Based on debugging work and an earlier patch from Brian Foster, who also wrote most of this changelog.

xfs: remote attribute blocks aren't really userdata
When adding a new remote attribute, we write the attribute to the new extent before the allocation transaction is committed. This means we cannot reuse busy extents as that violates crash consistency semantics. Hence we currently treat remote attribute extent allocation like userdata because it has the same overwrite ordering constraints as userdata.
Unfortunately, this also allows the allocator to incorrectly apply extent size hints to the remote attribute extent allocation. This results in interesting failures, such as transaction block reservation overruns and in-memory inode attribute fork corruption.
To fix this, we need to separate the busy extent reuse configuration from the userdata configuration. This changes the definition of XFS_BMAPI_METADATA slightly - it now means that allocation is metadata and reuse of busy extents is acceptible due to the metadata ordering semantics of the journal. If this flag is not set, it means the allocation is that has unordered data writeback, and hence busy extent reuse is not allowed. It no longer implies the allocation is for user data, just that the data write will not be strictly ordered. This matches the semantics for both user data and remote attribute block allocation.
As such, This patch changes the "userdata" field to a "datatype" field, and adds a "no busy reuse" flag to the field. When we detect an unordered data extent allocation, we immediately set the no reuse flag. We then set the "user data" flags based on the inode fork we are allocating the extent to. Hence we only set userdata flags on data fork allocations now and consider attribute fork remote extents to be an unordered metadata extent.
The result is that remote attribute extents now have the expected allocation semantics, and the data fork allocation behaviour is completely unchanged.
It should be noted that there may be other ways to fix this (e.g. use ordered metadata buffers for the remote attribute extent data write) but they are more invasive and difficult to validate both from a design and implementation POV. Hence this patch takes the simple, obvious route to fixing the problem...

xfs: set up per-AG free space reservations
One unfortunate quirk of the reference count and reverse mapping btrees -- they can expand in size when blocks are written to *other* allocation groups if, say, one large extent becomes a lot of tiny extents. Since we don't want to start throwing errors in the middle of CoWing, we need to reserve some blocks to handle future expansion. The transaction block reservation counters aren't sufficient here because we have to have a reserve of blocks in every AG, not just somewhere in the filesystem.
Therefore, create two per-AG block reservation pools. One feeds the AGFL so that rmapbt expansion always succeeds, and the other feeds all other metadata so that refcountbt expansion never fails.
Use the count of how many reserved blocks we need to have on hand to create a virtual reservation in the AG. Through selective clamping of the maximum length of allocation requests and of the length of the longest free extent, we can make it look like there's less free space in the AG unless the reservation owner is asking for blocks.
In other words, play some accounting tricks in-core to make sure that we always have blocks available. On the plus side, there's nothing to clean up if we crash, which is contrast to the strategy that the rough draft used (actually removing extents from the freespace btrees).

xfs: clean up XFS_MIN_FREELIST macros
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: xfs_alloc_fix_freelist() can use incore perag structures
At the moment, xfs_alloc_fix_freelist() uses a mix of per-ag based access and agf buffer based access to freelist and space usage information. However, once the AGF buffer is locked inside this function, it is guaranteed that both the in-memory and on-disk values are identical. xfs_alloc_fix_freelist() doesn't modify the values in the structures directly, so it is a read-only user of the infomration, and hence can use the per-ag structure exclusively for determining what it should do.
This opens up an avenue for cleaning up a lot of duplicated logic whose only difference is the structure it gets the data from, and in doing so removes a lot of needless byte swapping overhead when fixing up the free list.
