Message-Id: <20231027-vfs-ctime-6271b23ced64@brauner>
Date: Fri, 27 Oct 2023 16:51:07 +0200

Subject: [GIT PULL for v6.7] vfs time updates
Hey Linus,
This pull request will have a merge conflict with the vfs-6.7.super
pr that will be available under the following link once sent:
https://lore.kernel.org/r/20231027-vfs-super-aa4b9ecfd803@brauner
/* Summary */
This finishes the conversion of all inode time fields to accessor
functions as discussed on list. Changing timestamps manually as we used
to do before is error prone. Using accessors function makes this robust.
It does not contain the switch of the time fields to discrete 64 bit
integers to replace struct timespec and free up space in struct inode.
But after this, the switch can be trivially made and the patch should
only affect the vfs if we decide to do it.
/* Testing */
clang: Debian clang version 16.0.6 (16)
gcc: gcc (Debian 13.2.0-5) 13.2.0
All patches are based on v6.6-rc5 and have been sitting in linux-next.
No build failures or warnings were observed. xfstests were run for the
major filesystems. They pass.
/* Conflicts */
## Merge Conflicts with other trees
The following trees will have a merge conflict with this tree.
[1] linux-next: manual merge of the vfs-brauner tree with the ntfs3 tree
https://lore.kernel.org/r/20231010103744.2e7085a6@canb.auug.org.au
[2] linux-next: manual merge of the vfs-brauner tree with the ext3 tree
https://lore.kernel.org/r/20231027104356.3fda2bc9@canb.auug.org.au
[3] This will have a merge conflict with the btrfs and vfs.super trees.
The vfs.super tree does contain the btrfs tree this cycle and the
conflict resolution will be provided on the vfs-6.7.super pr as
mentioned above.
[4] For bcachefs a whole separate patch would be needed:
