Let me know if I've missed any. I've also pushed the pile to my tree as this tag: https://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux.git/tag/?h=ctime.20230705 In case that's easier to work with. Cheers,

Are there any preliminary patches showing what you want your introduced accessors to turn into? It is hard to judge the sanity of the introduction of wrappers without seeing what the wrappers are ultimately going to do. Eric

I picked up the series from the list and folded the fixups you posted here into the respective fs conversion patches. I hope that helps you avoid a resend. You should have received a separate "thank you" mail for all of this. To each patch that I folded one of the fixlets from below into I added a git note that records a link to your mail here and the respective patch hunk from this mail that I folded into the patch. git.kernel.org will show notes by default. For example, https://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs.git/commit/?h=vfs.ctime&id=8b0e3c2e99004609a16ba145bcbdfdddb78e220e should show you the note I added. You can also fetch them via git fetch $remote refs/notes/*:refs/notes/* (You probably know that ofc but jic.) if you're interested. Based on v6.5-rc1 as of today. Btw, both b4 and patchwork somehow treat the series in weird was. IOW, based on the message id of the cover letter I was able to pull most messages except for: [07/92] fs: add ctime accessors infrastructure [08/92] fs: new helper: simple_rename_timestamp [92/92] fs: rename i_ctime field to __i_ctime which I pulled in separately. Not sure what the cause of this is.

I ended up doing the send in two phases: one for the cover letter and infrastructure patches that went to everyone, and one for the per- subsystem patches that went do individual maintainers and lists. I suspect that screwed up the message IDs somehow. Hopefully I won't need to do a posting like that again soon, but I'll pay closer attention to the message id handling next time. Thanks again!

v2: - prepend patches to add missing ctime updates - add simple_rename_timestamp helper function - rename ctime accessor functions as inode_get_ctime/inode_set_ctime_* - drop individual inode_ctime_set_{sec,nsec} helpers I've been working on a patchset to change how the inode->i_ctime is accessed in order to give us conditional, high-res timestamps for the ctime and mtime. struct timespec64 has unused bits in it that we can use to implement this. In order to do that however, we need to wrap all accesses of inode->i_ctime to ensure that bits used as flags are appropriately handled. The patchset starts with reposts of some missing ctime updates that I spotted in the tree. It then adds a new helper function for updating the timestamp after a successful rename, and new ctime accessor infrastructure. The bulk of the patchset is individual conversions of different subsysteme to use the new infrastructure. Finally, the patchset renames the i_ctime field to __i_ctime to help ensure that I didn't miss anything. This should apply cleanly to linux-next as of this morning. Most of this conversion was done via 5 different coccinelle scripts, run in succession, with a large swath of by-hand conversions to clean up the remainder.
