There is a race when open sg with O_EXCL flag. Also a race may happen between sg_open and sg_remove.
Changes from v4: * [3/4] use ERR_PTR series instead of adding another parameter in sg_add_sfp * [4/4] fix conflict for cherry-pick from v3.
Changes from v3: * release o_sem in sg_release(), not in sg_remove_sfp(). * not set exclude with sfd_lock held.
Vaughan Cao (4): [SCSI] sg: use rwsem to solve race during exclusive open [SCSI] sg: no need sg_open_exclusive_lock [SCSI] sg: checking sdp->detached isn't protected when open [SCSI] sg: push file descriptor list locking down to per-device locking
