ocfs2: use flexible array in 'struct ocfs2_recovery_map'
Turn 'rm_entries' in 'struct ocfs2_recovery_map' into a flexible array.
The advantages are: - save the size of a pointer when the new undo structure is allocated - avoid some always ugly pointer arithmetic to get the address of 'rm_entries' - avoid an indirection when the array is accessed
While at it, use struct_size() to compute the size of the new undo structure.

ocfs2: fix memory leak in ocfs2_mount_volume()

This call stack is related to two problems. Firstly, the ocfs2 super uses "replay_map" to trace online/offline slots, in order to recover offline slots during recovery and mount. But when ocfs2_truncate_log_init() returns an error in ocfs2_mount_volume(), the memory of "replay_map" will not be freed in error handling path. Secondly, the memory of "replay_map" will not be freed if d_make_root() returns an error in ocfs2_fill_super(). But the memory of "replay_map" will be freed normally when completing recovery and mount in ocfs2_complete_mount_recovery().
Fix the first problem by adding error handling path to free "replay_map" when ocfs2_truncate_log_init() fails. And fix the second problem by calling ocfs2_free_replay_slots(osb) in the error handling path "out_dismount". In addition, since ocfs2_free_replay_slots() is static, it is necessary to remove its static attribute and declare it in header file.

ocfs2: fix mounting crash if journal is not alloced
Patch series "rewrite error handling during mounting stage".
This patch (of 5):
After commit da5e7c87827e8 ("ocfs2: cleanup journal init and shutdown"), journal init later than before, it makes NULL pointer access in free routine.
Crash flow:
ocfs2_fill_super + ocfs2_mount_volume | + ocfs2_dlm_init //fail & return, osb->journal is NULL. | + ... | + ocfs2_check_volume //no chance to init osb->journal | + ... + ocfs2_dismount_volume ocfs2_release_system_inodes ... evict ... ocfs2_clear_inode ocfs2_checkpoint_inode ocfs2_ci_fully_checkpointed time_after(journal->j_trans_id, ci->ci_last_trans) + journal is empty, crash!
For fixing, there are three solutions:
1> Partly revert commit da5e7c87827e8
For avoiding kernel crash, this make sense for us. We only concerned whether there has any non-system inode access before dlm init. The answer is NO. And all journal replay/recovery handling happen after dlm & journal init done. So this method is not graceful but workable.
2> Add osb->journal check in free inode routine (eg ocfs2_clear_inode)
The fix code is special for mounting phase, but it will continue working after mounting stage. In another word, this method adds useless code in normal inode free flow.
3> Do directly free inode in mounting phase
This method is brutal/complex and may introduce unsafe code, currently maintainer didn't like.
At last, we chose method <1> and did partly reverted job. We reverted journal init codes, and kept cleanup codes flow.

treewide: remove editor modelines and cruft
The section "19) Editor modelines and other cruft" in Documentation/process/coding-style.rst clearly says, "Do not include any of these in source files."
I recently receive a patch to explicitly add a new one.
Let's do treewide cleanups, otherwise some people follow the existing code and attempt to upstream their favoriate editor setups.
It is even nicer if scripts/checkpatch.pl can check it.
If we like to impose coding style in an editor-independent manner, I think editorconfig (patch [1]) is a saner solution.

jbd2: add support for avoiding data writes during transaction commits
Currently when filesystem needs to make sure data is on permanent storage before committing a transaction it adds inode to transaction's inode list. During transaction commit, jbd2 writes back all dirty buffers that have allocated underlying blocks and waits for the IO to finish. However when doing writeback for delayed allocated data, we allocate blocks and immediately submit the data. Thus asking jbd2 to write dirty pages just unnecessarily adds more work to jbd2 possibly writing back other redirtied blocks.
Add support to jbd2 to allow filesystem to ask jbd2 to only wait for outstanding data writes before committing a transaction and thus avoid unnecessary writes.

ocfs2: improve fsync efficiency and fix deadlock between aio_write and sync_file
Currently, ocfs2_sync_file grabs i_mutex and forces the current journal transaction to complete. This isn't terribly efficient, since sync_file really only needs to wait for the last transaction involving that inode to complete, and this doesn't require i_mutex.
Therefore, implement the necessary bits to track the newest tid associated with an inode, and teach sync_file to wait for that instead of waiting for everything in the journal to commit. Furthermore, only issue the flush request to the drive if jbd2 hasn't already done so.
This also eliminates the deadlock between ocfs2_file_aio_write() and ocfs2_sync_file(). aio_write takes i_mutex then calls ocfs2_aiodio_wait() to wait for unaligned dio writes to finish. However, if that dio completion involves calling fsync, then we can get into trouble when some ocfs2_sync_file tries to take i_mutex.

ocfs2: lighten up allocate transaction
The issue scenario is as following:
When fallocating a very large disk space for a small file, __ocfs2_extend_allocation attempts to get a very large transaction. For some journal sizes, there may be not enough room for this transaction, and the fallocate will fail.
The patch below extends & restarts the transaction as necessary while allocating space, and should work with even the smallest journal. This patch refers ext4 resize.

ocfs2: Revert 40bd62e to avoid regression in extended allocation
Revert commit 40bd62eb7fb8 ("fs/ocfs2/journal.h: add bits_wanted while calculating credits in ocfs2_calc_extend_credits").
Unfortunately this change broke fallocate even if there is insufficient disk space for the preallocation, which is a serious problem.

ocfs2: Add a missing journal credit in ocfs2_link_credits() -v2
With indexed_dir enabled, ocfs2 maintains a list of dirblocks having space.
The credit calculation in ocfs2_link_credits() did not correctly account for adding an entry that exactly fills a dirblock that triggers removing that dirblock by changing the pointer in the previous block in the list. The credit calculation did not account for that previous block.
To expose, do:
mkfs.ocfs2 -b 512 -M local /dev/sdX mount /dev/sdX /ocfs2 mkdir /ocfs2/linkdir touch /ocfs2/linkdir/file1 for i in `seq 1 29` ; do link /ocfs2/linkdir/file1 /ocfs2/linkdir/linklinklinklinklinklink$i; done rm -f /ocfs2/linkdir/linklinklinklinklinklink10 sleep 8 link /ocfs2/linkdir/file1 /ocfs2/linkdir/linklinklinklinklinklinkaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Note: The link names have been crafted for a 512 byte blocksize. Reproducing with a larger blocksize will require longer (or more) links. The sleep is important. We want jbd2 to commit the transaction so that the missing block does not piggy back on account of the previous transaction.

ocfs2: Fix estimate of necessary credits for mkdir
In the rare case that INLINE_DATA, INDEX_DIR, QUOTA, XATTR features are disabled and both the allocation of the directory inode and the allocation of the first directory block need to relink allocation group, there need not be enough credits reserved in a transaction. Fix the estimate.

ocfs2: Make ocfs2_journal_dirty() void.
jbd[2]_journal_dirty_metadata() only returns 0. It's been returning 0 since before the kernel moved to git. There is no point in checking this error.
ocfs2_journal_dirty() has been faithfully returning the status since the beginning. All over ocfs2, we have blocks of code checking this can't fail status. In the past few years, we've tried to avoid adding these checks, because they are pointless. But anyone who looks at our code assumes they are needed.
Finally, ocfs2_journal_dirty() is made a void function. All error checking is removed from other files. We'll BUG_ON() the status of jbd2_journal_dirty_metadata() just in case they change it someday. They won't.

ocfs2: Grow discontig block groups in one transaction.
Rather than extending the transaction every time we add an extent to a discontiguous block group, we grab enough credits to fill the extent list up front. This means we can free the bits in the same transaction if we end up not getting enough space.
