To pick the changes in:
99668f6180 ("fs: expose LOOKUP_CACHED through openat2() RESOLVE_CACHED")
That don't result in any change in tooling, only silences this perf

* Arguments for how openat2(2) should open the target path. If only @flags and
|

* @mode are non-zero, then openat2(2) operates very similarly to openat(2).
|
|
*
|
|
* However, unlike openat(2), unknown or invalid bits in @flags result in
|
|
* -EINVAL rather than being silently ignored. @mode must be zero unless one of
|
|
* {O_CREAT, O_TMPFILE} are set.
|
|
*
|
|
* @flags: O_* flags.
|
|
* @mode: O_CREAT/O_TMPFILE file mode.
|
|
* @resolve: RESOLVE_* flags.
