Hi all,
this series moves the extent count and format fields into the xfs_ifork
structure. It is based on the "dinode reading cleanups v2" series.
Git tree:
git://git.infradead.org/users/hch/xfs.git xfs-ifork-cleanup.2
Gitweb:
http://git.infradead.org/users/hch/xfs.git/shortlog/refs/heads/xfs-ifork-cleanup.2
Changes since v1:
- pick up a different scrub prep patch from Darrick
- keep the nextents == 0 assert in xfs_attr_fork_remove
- keep clearing various ifork fields in xfs_ifork_destroy
- add more comments

XFS_IFORK_Q is supposed to be a predicate, not a function returning a
value. Its usage is in xchk_bmap_check_rmaps is incorrect, but that
function only cares about whether or not the "size" of the data is zero
or not. Convert that logic to use a proper boolean, and teach the
caller to skip the call entirely if the end result would be that we'd do
nothing anyway. This avoids a crash later in this series.

xfs_ifree only need to free inline data in the data fork, as we've
already taken care of the attr fork before (and in fact freed the
fork structure). Just open code the freeing of the inline data.

There are there are three extents counters per inode, one for each of
the forks. Two are in the legacy icdinode and one is directly in
struct xfs_inode. Switch to a single counter in the xfs_ifork structure
where it uses up padding at the end of the structure. This simplifies
various bits of code that just wants the number of extents counter and
can now directly dereference it.

From: Christoph Hellwig @ 2020-05-18 7:33 UTC (permalink / raw)
To: linux-xfs; +Cc: Brian Foster, Chandan Babu R
Both the data and attr fork have a format that is stored in the legacy
idinode. Move it into the xfs_ifork structure instead, where it uses
up padding.

Move freeing the dynamically allocated attr and COW fork, as well
as zeroing the pointers where actually needed into the callers, and
just pass the xfs_ifork structure to xfs_idestroy_fork. Also simplify
the kmem_free calls by not checking for NULL first.

I'm still rather confused about the i_size logic, but this seems like a
good cleanup regardless:
