gfs2: fix flock panic issue
Commit 4f6563677ae8 ("Move locks API users to locks_lock_inode_wait()") moved flock/posix lock identify code to locks_lock_inode_wait(), but missed to set fl_flags to FL_FLOCK which will cause kernel panic in locks_lock_inode_wait(). Fixes: 4f6563677ae8 ("Move locks API users to locks_lock_inode_wait()") Signed-off-by: Junxiao Bi <junxiao.bi@oracle.com> Signed-off-by: Bob Peterson <rpeterso@redhat.com>
