Subject: [PATCH 0/6 v2] Change ->mkdir() and vfs_mkdir() to return a dentry
Date: Thu, 27 Feb 2025 12:32:52 +1100	[thread overview]
Message-ID: <20250227013949.536172-1-neilb@suse.de> (raw)

This revised series contains a few clean-ups as requested by various
people but no substantial changes.

It is based on vfs/vfs-6.15.async.dir plus vfs/vfs-6.15.sysv: I dropped the
change to sysv as it seemed pointless preserving them.

I reviewed the mkdir functions in many (all?) filesystems and found a
few that use d_instantiate() on an unlocked inode (after
unlock_new_inode()) and also support export_operations.  These could
potentially call d_instantiate() on a directory inode which is already
attached to an dentry, though making that happen would usually require
guessing the filehandle correctly.  I haven't tried to address those
here, (this patch set doesn't make that situation any worse) but I may
in the future.

Thanks,
NeilBrown
