The following patch for megaraid_sas fixes the LD/VF affiliation policy parsing code to account for LD targetId's and Hidden LD's (not yet affiliated with any Virtual Functions). This also breaks megasas_get_ld_vf_affiliation() into 2 separate functions: megasas_get_ld_vf_affiliation_111() and megasas_get_ld_Vf_affiliation_12() to reduce indentation levels. Signed-off-by:

Give existing errors priority over the generation of Task Set Full (TSF) errors. So that max_queue is not exceeded, existing errors may be sent back in the invocation thread. This is done so errors like Unit Attentions are not hidden and lost by either max_queue exceeded or real/injected TSFs. Signed-off-by:

This patch removes a NULL check for the scsi_cmnd::cmnd pointer since many other instances in this driver and elsewhere assume it is valid. Also redundant casts to 'unsigned char *' are removed as the pointer has that type. Signed-off-by:

When a second(kdump) kernel starts and the hard reset method is used the driver calls pci_disable_device without previously enabling it, so the kernel shows a warning - [ 16.876248] WARNING: at drivers/pci/pci.c:1431 pci_disable_device+0x84/0x90() [ 16.882686] Device hpsa disabling already-disabled device ... This patch fixes it, in addition to this I tried to balance also some other pairs of enable/disable device in the driver. Unfortunately I wasn't able to verify the functionality for the case of a sw reset, because of a lack of proper hw. Signed-off-by:

Rounding up to a multiple of 4 should be done using the ALIGN macro. As a bonus, this also makes the generated code smaller.

SCSI Well-known logical units generally don't have any scsi driver associated with it which means no one will call scsi_autopm_put_device() on these wlun scsi devices and this would result in keeping the corresponding scsi device always active (hence LLD can't be suspended as well). Same exact problem can be seen for other scsi device representing normal logical unit whose driver is yet to be loaded. This patch fixes the above problem with this approach: - make the scsi_autopm_put_device call at the end of scsi_sysfs_add_sdev to make it balance out the get earlier in the function. - let drivers do paired get/put calls in their probe methods.

The SCSI specification requires that the second Command Data Byte should contain the LUN value in its high-order bits if the recipient device reports SCSI level 2 or below. Nevertheless, some USB mass-storage devices use those bits for other purposes in vendor-specific commands. Currently Linux has no way to send such commands, because the SCSI stack always overwrites the LUN bits. Testing shows that Windows 7 and XP do not store the LUN bits in the CDB when sending commands to a USB device. This doesn't matter if the device uses the Bulk-Only or UAS transports (which virtually all modern USB mass-storage devices do), as these have a separate mechanism for sending the LUN value. Therefore this patch introduces a flag in the Scsi_Host structure to inform the SCSI midlayer that a transport does not require the LUN bits to be stored in the CDB, and it makes usb-storage set this flag for all devices using the Bulk-Only transport. (UAS is handled by a separate driver, but it doesn't really matter because no SCSI-2 or lower device is at all likely to use UAS.) The patch also cleans up the code responsible for storing the LUN value by adding a bitflag to the scsi_device structure. The test for whether to stick the LUN value in the CDB can be made when the device is probed, and stored for future use rather than being made over and over in the fast path. Signed-off-by:

Add a use_cmd_list flag in struct Scsi_Host to request keeping track of all outstanding commands per device. Default behaviour is not to keep track of cmd_list per sdev, as this may introduce lock contention. (overhead is more on multi-node NUMA.), and only enable it on the two drivers that need it.

This patches fixes a potential buffer overrun in __iscsi_conn_send_pdu. This function is used by iscsi drivers and userspace to send iscsi PDUs/ commands. For login commands, we have a set buffer size. For all other commands we do not support data buffers.

Commit 9226b5b4 ("vfs: avoid non-forwarding large load after small store in path lookup") made link_path_walk() always access the "hash_len" field as a single 64-bit entity, in order to avoid mixed size accesses to the members. However, what I didn't notice was that that effectively means that the whole "struct qstr this" is now basically redundant. We already explicitly track the "const char *name", and if we just use "u64 hash_len" instead of "long len", there is nothing else left of the "struct qstr". We do end up wanting the "struct qstr" if we have a filesystem with a "d_hash()" function, but that's a rare case, and we might as well then just squirrell away the name and hash_len at that point. End result: fewer live variables in the loop, a smaller stack frame, and better code generation. And we don't need to pass in pointers variables to helper functions any more, because the return value contains all the relevant information. So this removes more lines than it adds, and the source code is clearer too. Signed-off-by:
