[GIT PULL 11/18 for v7.3] vfs lookup
From: Christian Brauner
Date: Fri Aug 14 2026 - 09:14:32 EST
Hey Linus,
/* Summary */
This refactors lookup_open() and adds vfs_lookup_open() for nfsd.
mnt_want_write() and parent locking are moved into lookup_open()
itself.
audit_inode_child() is also now called in lookup_open() on failure. That
is the calling convention in vfs_create() and vfs_mkdir(), but
lookup_open() made no such call when atomic_open() should have created a
file and did not. And neither did the regular ->create() path fwiw.
This also contains work to remove the unneded excl argument from the
->create() inode op.
/* Testing */
No build failures or warnings were observed.
/* Conflicts */
