reduce libxfs to kernel differences

reduce libxfs to kernel differences

[Christoph Hellwig]

Hi all,

this series cleans up libxfs to further reduce the difference to
the kernel version, and to reuse xfs_trans.h and the various log item
headers that my kernel series moved to libxfs.

Note that in this series, it uses the Linux 7.2 versions of the kernel
headers as libxfs hasn't been resynced with 7.3 yet.

[PATCH 01/13] libxfs: use libxfs.h in xfs_platform.h

[Christoph Hellwig]

xfs_platform.h duplicates a lot of the include chains and some of the
definitions in include/libxfs.h.  Use that header from xfs_plaform.h and
remove the duplication.

[PATCH 10/13] libxfs: use xfs_buf_item.h and xfs_inode_item.h from the kernel source

[PATCH 11/13] libxfs: cleanup xfs_trans.h

[Christoph Hellwig]

Add new xfs_trans_priv.h and xfs_log.h stubs for definitions that aren't
in xfs_trans.h in the kernel.  This prepares for pulling in the kernel
version of xfs_trans.h.

after this, inode.c, init.c, and logitem.c all #include "xfs_trans.h" twice?

and trans.c includes xfs_buf_item.h twice.

(perhaps the existing #includes just needed to be moved up?)


Also after this I think we have both libxfs/xfs_trans.h and libxfs/stubs/xfs_trans.h
with the same guard, did you mean to remove the one in stubs/ ?

(ugh, why do I sound like Sashiko LOL)

Some need to be moved up, some are just duplicate.  I made a bit of
a mess splitting up my original bigger patch which resulted in this.

The same mess as above left the old xfs_trans.h around in the patch as I
only removed it locally after fixing up the split..

You sound way more human!

[PATCH 13/13] libxfs: use all log item headers from the kernel

[Christoph Hellwig]

Wire up all the xfs_*_item.h headers from the kernel instead of
duplicating the definitions.

This looks fine to me, though same as the previous patchset I'll let
Carlos and Andrey figure out which libxfsification they want to merge.

reduce libxfs to kernel differences v2

[Christoph Hellwig]

Hi all,

this series cleans up libxfs to further reduce the difference to
the kernel version, and to reuse xfs_trans.h and the various log item
headers that my kernel series moved to libxfs.

Note that in this series, it uses the Linux 7.2 versions of the kernel
headers as libxfs hasn't been resynced with 7.3 yet.

Changes since v1:
 - really remove the old xfs_trans.h
 - juggle various includes around and remove several that are not needed

[PATCH 11/13] libxfs: cleanup xfs_trans.h

[Christoph Hellwig]

Add new xfs_trans_priv.h and xfs_log.h stubs for definitions that aren't
in xfs_trans.h in the kernel.  This prepares for pulling in the kernel
version of xfs_trans.h.
