Merge branch 'work.namei' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs into for-5.12/io_uring
Merge RESOLVE_CACHED bits from Al, as the io_uring changes will build on
top of that.
* 'work.namei' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
fs: expose LOOKUP_CACHED through openat2() RESOLVE_CACHED
fs: add support for LOOKUP_CACHED
saner calling conventions for unlazy_child()
fs: make unlazy_walk() error handling consistent
fs/namei.c: Remove unlikely of status being -ECHILD in lookup_fast()
do_tmpfile(): don't mess with finish_open()
