* dmaengine: mv_xor: add support for a38x command in descriptor modeLior Amsalem2015-06-103-15/+76
| | | | | | | | | | | | | | | | | | The Marvell Armada 38x SoC introduce new features to the XOR engine, especially the fact that the engine mode (MEMCPY/XOR/PQ/etc) can be part of the descriptor and not set through the controller registers. This new feature allows mixing of different commands (even PQ) on the same channel/chain without the need to stop the engine to reconfigure the engine mode. Refactor the driver to be able to use that new feature on the Armada 38x, while keeping the old behaviour on the older SoCs.

* dmaengine: mv_xor: bug fix for racing condition in descriptors cleanupLior Amsalem2015-06-102-26/+47
| | | | | | | | | | | | | | | | This patch fixes a bug in the XOR driver where the cleanup function can be called and free descriptors that never been processed by the engine (which result in data errors). The cleanup function will free descriptors based on the ownership bit in the descriptors.

| | | | | | | | | | | | | | | | | | add support for new CSR atlas7 SoC. atlas7 exists V1 and V2 IP. atlas7 DMAv1 is basically moved from marco, which has never been delivered to customers and renamed in this patch. atlas7 DMAv2 supports chain DMA by a chain table, this patch also adds chain DMA support for atlas7. atlas7 DMAv1 and DMAv2 co-exist in the same chip. there are some HW configuration differences(register offset etc.) with old prima2 chips, so we use compatible string to differentiate old prima2 and new atlas7, then results in different set in HW for them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The estimate of necessary transaction credits in ext4_flex_group_add() is too pessimistic. It reserves credit for sb, resize inode, and resize inode dindirect block for each group added in a flex group although they are always the same block and thus it is enough to account them only once. Also the number of modified GDT block is overestimated since we fit EXT4_DESC_PER_BLOCK(sb) descriptors in one block. Make the estimation more precise. That reduces number of requested credits enough that we can grow 20 MB filesystem (which has 1 MB journal, 79 reserved GDT blocks, and flex group size 16 by default).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently it is possible to lose whole file system block worth of data when we hit the specific interaction with unwritten and delayed extents in status extent tree. The problem is that when we insert delayed extent into extent status tree the only way to get rid of it is when we write out delayed buffer. However there is a limitation in the extent status tree implementation so that when inserting unwritten extent should there be even a single delayed block the whole unwritten extent would be marked as delayed. At this point, there is no way to get rid of the delayed extents, because there are no delayed buffers to write out. So when a we write into said unwritten extent we will convert it to written, but it still remains delayed. When we try to write into that block later ext4_da_map_blocks() will set the buffer new and delayed and map it to invalid block which causes the rest of the block to be zeroed loosing already written data. For now we can fix this by simply not allowing to set delayed status on written extent in the extent status tree. Also add WARN_ON() to make sure that we notice if this happens in the future. This problem can be easily reproduced by running the following xfs_io. xfs_io -f -c "pwrite -S 0xaa 4096 2048" \ -c "falloc 0 131072" \ -c "pwrite -S 0xbb 65536 2048" \ -c "fsync" /mnt/test/fff echo 3 > /proc/sys/vm/drop_caches xfs_io -c "pwrite -S 0xdd 67584 2048" /mnt/test/fff This can be theoretically also reproduced by at random by running fsx, but it's not very reliable, though on machines with bigger page size (like ppc) this can be seen more often (especially xfstest generic/127) Signed-off-by: Lukas Czerner <lczerner@redhat.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu> Cc: stable@vger.kernel.org

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The number of relocs is passed in by userspace and can be large. It has been observed to cause kcalloc failures in the wild.

The 3ware class of drivers were causing an oops with multiqueue by tearing down the command mappings after completing the command (where the variables in the command used to tear down the mapping were no-longer valid). There's also a fix for the qnap iscsi target which was choking on us sending it commands that were too long and a fix for the reworked aha1542 allocating GFP_KERNEL under a lock" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: 3w-9xxx: fix command completion race 3w-xxxx: fix command completion race 3w-sas: fix command completion race aha1542: Allocate memory before taking a lock SCSI: add 1024 max sectors black list flag

Also remove the dma mapping helpers which have another inherent race due to the request_id index.
