Hi Linus,

/* Summary */
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.

/* Testing */
All patches are based on v5.13-rc4 and have been sitting in linux-next. No
build failures or warnings were observed. All old and new tests are passing.

/* Conflicts */
At the time of creating this PR no merge conflicts were reported from
linux-next and no merge conflicts showed up doing a test-merge with current
mainline.

The following changes since commit 8124c8a6b35386f73523d27eacb71b5364a68c4c:
