Subject[PATCH v5 0/4] [SCSI] sg: fix race condition in sg_open
Date
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
