2016-10-20xfs: don't take the IOLOCK exclusive for direct I/O page invalidationChristoph Hellwig
XFS historically took the iolock exclusive when invalidating pages before direct I/O operations to protect against writeback starvations. But this writeback starvation issues has been fixed a long time ago in the core writeback code, and all other file systems manage to do without the exclusive lock. Convert XFS over to avoid the exclusive lock in this case, and also move to range invalidations like done by the other file systems.

target_complete_cmd_with_length" This reverts commit c1ccbfe0311e2380a6d2dcb0714b36904f5d586f. Reverting this patch, as it incorrectly assumes the additional length for INQUIRY in target_complete_cmd_with_length() is SCSI allocation length, which breaks existing user-space code when SCSI allocation length is smaller than additional length. root@scsi-mq:~# sg_inq --len=4 -vvvv /dev/sdb found bsg_major=253 open /dev/sdb with flags=0x800 inquiry cdb: 12 00 00 00 04 00 duration=0 ms inquiry: pass-through requested 4 bytes (data-in) but got -28 bytes inquiry: pass-through can't get negative bytes, say it got none inquiry: got too few bytes (0) INQUIRY resid (32) should never exceed requested len=4 inquiry: failed requesting 4 byte response: Malformed response to SCSI command [resid=32] AFAICT the original change was not to address a specific host issue, so go ahead and revert to original logic for now.

2016-10-19target: Don't override EXTENDED_COPY xcopy_pt_cmd SCSI status codeDinesh Israni
This patch addresses a bug where a local EXTENDED_COPY WRITE or READ backend I/O request would always return SAM_STAT_CHECK_CONDITION, even if underlying xcopy_pt_cmd->se_cmd generated a different SCSI status code. ESX host environments expect to hit SAM_STAT_RESERVATION_CONFLICT for certain scenarios, and SAM_STAT_CHECK_CONDITION results in non-retriable status for these cases. Tested on v4.1.y with ESX v5.5u2+ with local IBLOCK backend copy.

2016-10-19target: Make EXTENDED_COPY 0xe4 failure return COPY TARGET DEVICE NOT REACHABLENicholas Bellinger
This patch addresses a bug where EXTENDED_COPY across multiple LUNs results in a CHECK_CONDITION when the source + destination are not located on the same physical node. ESX Host environments expect sense COPY_ABORTED w/ COPY TARGET DEVICE NOT REACHABLE to be returned when this occurs, in order to signal fallback to local copy method. As described in section 6.3.3 of spc4r22: "If it is not possible to complete processing of a segment because the copy manager is unable to establish communications with a copy target device, because the copy target device does not respond to INQUIRY, or because the data returned in response to INQUIRY indicates an unsupported logical unit, then the EXTENDED COPY command shall be terminated with CHECK CONDITION status, with the sense key set to COPY ABORTED, and the additional sense code set to COPY TARGET DEVICE NOT REACHABLE."

2016-10-19target: Re-add missing SCF_ACK_KREF assignment in v4.1.yNicholas Bellinger
This patch fixes a regression in >= v4.1.y code where the original SCF_ACK_KREF assignment in target_get_sess_cmd() was dropped upstream in commit 054922bb, but the series for addressing TMR ABORT_TASK + LUN_RESET with fabric session reinstatement in commit febe562c20 still depends on this code in transport_cmd_finish_abort(). The regression manifests itself as a se_cmd->cmd_kref +1 leak, where ABORT_TASK + LUN_RESET can hang indefinately for a specific I_T session for drivers using SCF_ACK_KREF, resulting in hung kthreads. This patch has been verified with v4.1.y code.

2016-10-20ubifs: Abort readdir upon errorRichard Weinberger
If UBIFS is facing an error while walking a directory, it reports this error and ubifs_readdir() returns the error code. But the VFS readdir logic does not make the getdents system call fail in all cases. When the readdir cursor indicates that more entries are present, the system call will just return and the libc wrapper will try again since it also knows that more entries are present. This causes the libc wrapper to busy loop for ever when a directory is corrupted on UBIFS. A common approach do deal with corrupted directory entries is skipping them by setting the cursor to the next entry. On UBIFS this approach is not possible since we cannot compute the next directory entry cursor position without reading the current entry. So all we can do is setting the cursor to the "no more entries" position and make getdents exit. Cc: stable@vger.kernel.org Signed-off-by: Richard Weinberger <richard@nod.at>

Now that we've make skl_wm_levels make a little more sense, we can remove all of the redundant wm information. Up until now we'd been storing two copies of all of the skl watermarks: one being the skl_pipe_wm structs, the other being the global wm struct in drm_i915_private containing the raw register values. This is confusing and problematic, since it means we're prone to accidentally letting the two copies go out of sync.

2016-10-19nvme.h: resync with nvme-cliChristoph Hellwig
Import a few updates to nvme.h from nvme-cli. This mostly includes a few new fields and error codes, but also a few renames that so far are only used in user space. Also one field is moved from an array of two le64 values to one of 16 u8 values so that we can more easily access it.

2016-10-19pmem: report error on clear poison failureToshi Kani
ACPI Clear Uncorrectable Error DSM function may fail or may be unsupported on a platform. pmem_clear_poison() returns without clearing badblocks in such cases. This failure is detected at the next read (-EIO). This behavior can lead to an issue when user keeps writing but does not read immediately. For instance, flight recorder file may be only read when it is necessary for troubleshooting. Change pmem_do_bvec() and pmem_clear_poison() to return -EIO so that filesystem can log an error message on a write error.

We should only try to allocate multiple MSI or MSI-X vectors if the device actually has multiple ports. Otherwise pci_alloc_irq_vectors will return a single vector due to n_ports = 1, in which case we shouldn't set the AHCI_HFLAG_MULTI_MSI flag.

2016-10-19ARC: Adjust cpuinfo for non-continuous cpu idsNoam Camus
num_possible_cpus() returns how many CPUs may be present on system. However we want the highest possible CPU number. This may be differ in a sparsed possible CPUs map. Such map achived by OF for plat-eznps. For example if we have: possible cpus mask 0,3 Then: num_possible_cpus() is equal 2 while nr_cpu_ids is equal 4. Only for value 4 c_start() will provide correct cpuinfo at procfs. Signed-off-by: Noam Camus <noamc@ezchip.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
