vfs: Remove duplicated d_mountpoint check in __is_local_mountpoint
This function acts as an out-of-line helper for is_local_mountpoint is only called after the latter verifies the dentry is not a mountpoint. There's no semantic changes and the resulting object code is smaller: add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-26 (-26) Function old new delta __is_local_mountpoint 147 121 -26 Total: Before=34161, After=34135, chg -0.08% Signed-off-by: Nikolay Borisov <nborisov@suse.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
