[PATCH linux dev-6.1 0/5] Backports to support OpenBMC with IMA

[Stefan Berger]

This series of patches are backports from recent extensions to core Linux
filesystem code (support for STATX_CHANGE_COOKIE) and subsequent fixes
to IMA and overlayfs so that IMA can be used by OpenBMC configured with
overlayfs. Overlayfs is for example used by the p10bmc build.

The patches in this series have been cherry-picked from upstream Linux
using the following commands:

git cherry-pick 131f4fd2c25a # 3 consecutive patches of longer series
git cherry-pick a3bb710383cb
git cherry-pick a1175d6b1bda
git cherry-pick db1d1e8b9867 # IMA: use vfs_getattr_nosec ...
git cherry-pick 18b44bc5a672 # ovl: Always reevaluate ...

Regards,
   Stefan

Eric Snowberg (1):
  ovl: Always reevaluate the file signature for IMA

Jeff Layton (4):
  fs: uninline inode_query_iversion
  fs: clarify when the i_version counter must be updated
  vfs: plumb i_version handling into struct kstat
  IMA: use vfs_getattr_nosec to get the i_version
