Merge tag 'fs.mount_setattr.nosymfollow.v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull mount_setattr updates from Christian Brauner:
"A few releases ago the old mount API gained support for a mount
options which prevents following symlinks on a given mount. This adds
support for it in the new mount api through the MOUNT_ATTR_NOSYMFOLLOW
flag via mount_setattr() and fsmount(). With mount_setattr() that flag
can even be applied recursively.
There's an additional ack from Ross Zwisler who originally authored
the nosymfollow patch. As I've already had the patches in my for-next
I didn't add his ack explicitly"
* tag 'fs.mount_setattr.nosymfollow.v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux:
tests: test MOUNT_ATTR_NOSYMFOLLOW with mount_setattr()
mount: Support "nosymfollow" in new mount api
