2018-10-16IB/mlx4: Refer to the device kobject instead of ports_parentParav Pandit
iov sysfs tree is created under ib device at /sys/class/infiniband/mlx4_0/iov. And, ibdev->ports_parent->parent = &ibdev->dev. Therefore, refer to device's kobject directly instead of indirect access to it. Additionally, iov entries are created under device kobject and deleted before device is removed. There is no need to hold additional reference to device kobject in provider driver.

And driver will clear the checksum of the header after doing DMA map, so HW will read the old header whose L3 checksum is not cleared and calculate a wrong L3 checksum.

2018-10-16qed: Align local and global PTT to propagate through the APIs.Rahul Verma
Align the use of local PTT to propagate through the qed_mcp* API's. Global ptt should not be used. Register access should be done through layers. Register address is mapped into a PTT, PF translation table. Several interface functions require a PTT to direct read/write into register. There is a pool of PTT maintained, and several PTT are used simultaneously to access device registers in different flows. Same PTT should not be used in flows that can run concurrently. To avoid running out of PTT resources, too many PTT should not be acquired without releasing them. Every PF has a global PTT, which is used throughout the life of PF, in most important flows for register access. Generic functions acquire the PTT locally and release after the use. This patch aligns the use of Global PTT and Local PTT accordingly. Signed-off-by: Rahul Verma <rahul.verma@cavium.com> Signed-off-by: Ariel Elior <ariel.elior@cavium.com> Signed-off-by: David S.

Commit ea7e0480a4b6 ("MIPS: VDSO: Always map near top of user memory") set VDSO_RANDOMIZE_SIZE to 256MB for 64bit kernel. But take a look at arch/mips/mm/mmap.c we can see that MIN_GAP is 128MB, which means the mmap_base may be at (user_address_top - 128MB). This make the stack be surrounded by mmaped areas, then stack expanding fails and causes a segmentation fault. Therefore, VDSO_RANDOMIZE_SIZE should be less than MIN_GAP and this patch reduce it to 64MB.

Note that, it requires "f2fs: return correct errno in f2fs_gc". This adds a lightweight non-persistent snapshotting scheme to f2fs. To use, mount with the option checkpoint=disable, and to return to normal operation, remount with checkpoint=enable. If the filesystem is shut down before remounting with checkpoint=enable, it will revert back to its apparent state when it was first mounted with checkpoint=disable.

2018-10-16sx8: convert to blk-mqJens Axboe
Convert from the old request_fn style driver to blk-mq. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2018-10-16z2ram: convert to blk-mqJens Axboe
Straight forward conversion to blk-mq, nothing special about this driver. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2018-10-16gdrom: convert to blk-mqJens Axboe
Ditch the deffered list, lock, and workqueue handling. Just mark the set as being blocking, so we are invoked from a workqueue already. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2018-10-16floppy: convert to blk-mqOmar Sandoval
This driver likes to fetch requests from all over the place, so make queue_rq put requests on a list so that the logic stays the same. Tested with QEMU. Signed-off-by: Omar Sandoval <osandov@fb.com> Converted to blk_mq_init_sq_queue() and fixed a few spots where the tag_set leaked on cleanup. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2018-10-16ataflop: convert to blk-mqOmar Sandoval
This driver is already pretty broken, in that it has two wait_events() (one in stdma_lock()) in request_fn. Get rid of the first one by freezing/quiescing the queue on format, and the second one by replacing it with stdma_try_lock(). The rest is straightforward. Compile-tested only and probably incorrect.

2018-10-16ataflop: fix error handling during setupOmar Sandoval
Move queue allocation next to disk allocation to fix a couple of issues: - If add_disk() hasn't been called, we should clear disk->queue before calling put_disk(). - If we fail to allocate a request queue, we still need to put all of the disks, not just the ones that we allocated queues for.

2018-10-16ataflop: fold headers into C fileOmar Sandoval
atafd.h and atafdreg.h are only used from ataflop.c, so merge them in there. Signed-off-by: Omar Sandoval <osandov@fb.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2018-10-16amiflop: convert to blk-mqOmar Sandoval
Straightforward conversion, just use the existing amiflop_lock to serialize access to the controller. Compile-tested only. Cc: Laurent Vivier <lvivier@redhat.com> Signed-off-by: Omar Sandoval <osandov@fb.com> Converted to blk_mq_init_sq_queue() Signed-off-by: Jens Axboe <axboe@kernel.dk>
2018-10-16amiflop: clean up on errors during setupOmar Sandoval
The error handling in fd_probe_drives() doesn't clean up at all. Fix it up in preparation for converting to blk-mq. While we're here, get rid of the commented out amiga_floppy_remove(). Signed-off-by: Omar Sandoval <osandov@fb.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
