commit fd493350bb6045819987c391f2c5dbfd1a44cb63 Author: He Zhe Date: Thu Jul 29 14:53:56 2021 +0800 aufs: i_op: Add handling for au_pin_hdir_set_owner with RT kernel In RT kernel rw_semaphore uses rt_mutex whose owner should be set to the task. Add a condition to handle both cases. fs/aufs/i_op.c: In function 'au_pin_hdir_set_owner': fs/aufs/i_op.c:627:52: error: 'struct rw_semaphore' has no member named 'owner' 627 | atomic_long_set(&p->hdir->hi_inode->i_rwsem.owner, (long)task); | ^ Signed-off-by: He Zhe Signed-off-by: J.
