[PATCH v2 0/4] xfs: consolidate metadir creation code

[PATCH v2 0/4] xfs: consolidate metadir creation code

[Johannes Thumshirn]

The XFS metadata directory tree has grown several nearly identical
open-coded copies of the "create a metadata inode" sequence: allocate the
creation transaction, create and link the inode, do a bit of type
specific inode setup, commit, and finish or tear down the inode on both
the success and error paths.

Factor that boilerplate into a single helper, xfs_metadir_create_file(),
which takes the file mode and an optional callback to finish initializing
the new inode inside the creation transaction, and convert the existing
users - xfs_metadir_mkdir(), the quota inodes and the rtgroup inodes -
over to it.

Having a single helper also makes it straightforward to add new metadata
inode types without copying the sequence yet again.

No functional change intended otherwise.

Changes to v1:
- Re-based onto xfs/for-next HEAD: f88caa121eac ("xfs: use xfs_csn_t for xlog_cil_push_now() push_seq parameter")
- Added patch 4/4
- Added Christoph's review

Johannes Thumshirn (4):
  xfs: add xfs_metadir_create_file helper
  xfs: create quota metadir inodes using xfs_metadir_create_file
  xfs: create rtgroup metadir inodes using xfs_metadir_create_file
  xfs: mark internal metadir file creation helpers static

[PATCH v2 1/4] xfs: add xfs_metadir_create_file helper

[Johannes Thumshirn]

Factor the metadata inode create/commit/cleanup lifecycle out of
xfs_metadir_mkdir into a reusable helper that takes an optional callback
to initialize the new inode, and convert xfs_metadir_mkdir to it.

I'd have called these both "_create_fn" and "create_fn" for consistency
but otherwise this looks fine to me.

Though I guess we already have ->create for rtgroup inodes.  I can't
think of a good (re)naming scheme for both ... but the parameters are at
least different so I guess this is fine.

[PATCH v2 4/4] xfs: mark internal metadir file creation helpers static

[Johannes Thumshirn]

Now that there is xfs_metadir_create_file() mark
xfs_metadir_start_create(), xfs_metadir_create() and xfs_metadir_cancel()
as static and remove them from xfs_metadir.h.
