staging: lustre: ldlm: crash on umount in cleanup_resource
cfs_hash_for_each_relax() assumes that cfs_hash_put_locked() doesn't release bd lock, but it isn't true for ldlm_res_hop_put_locked(). Add recfcount on next hnode in cfs_hash_for_each_relax() and remove ldlm_res_hop_put_locked() Signed-off-by: Andriy Skulysh <andriy.skulysh@seagate.com> Intel-bug-id: https://jira.hpdd.intel.com/browse/LU-6304 Xyratex-bug-id: MRP-2352 Reviewed-by: Vitaly Fertman <vitaly.fertman@seagate.com> Reviewed-by: Alexander Boyko <alexander.boyko@seagate.com> Tested-by: Alexander Lezhoev <alexander.lezhoev@seagate.com> Reviewed-on: http://review.whamcloud.com/13908Reviewed-by: Oleg Drokin <oleg.drokin@intel.com> Signed-off-by: James Simmons <jsimmons@infradead.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
