Instead of having a separate makefile, and be alone, group it at the SCSI documentation and make it being built as part of docs makefile. Link: https://lore.kernel.org/r/419c455fb40c9a1e85cc9a654a7fdb07aeeccf71.1583136624.git.mchehab+huawei@kernel.orgSigned-off-by:

In preparation for adding the SCSI documents to the documentation body, add an empty index for it. The next patches should be adding contents to it, as files get converted to ReST format.

Having this log in a ring buffer helps to diagnose qla2xxx driver and firmware issues instead of having to reproduce the problem with extended_logging enabled. This saves cycles and helps when it is hard to reproduce problem. Link: https://lore.kernel.org/r/1581557368-32080-1-git-send-email-rajan.shanmugavelu@oracle.comReviewed-by:

Device quirk "UFS_DEVICE_QUIRK_HOST_PA_TACTIVATE" is enabled for all Samsung devices by default currently. However MediaTek UFS host requires different host PA_TACTIVATE configuration. Hence clear this quirk first and then apply vendor-specific value in vops callback. Link: https://lore.kernel.org/r/20200302135346.16797-1-stanley.chu@mediatek.comReviewed-by:

When driver debugging is not enabled, change the debug print macros to use the no_printk() macro. This fixes a gcc warning when -Wextra is set: ../drivers/message/fusion/mptlan.c:266:39: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body] I have verified that there is very little object code change (with gcc 7.5.0).

iSCSI session destruction can be arbitrarily slow, since it might require network operations and serialization inside the SCSI layer. This patch adds a new user event to trigger the destruction work asynchronously, releasing the rx_queue_mutex as soon as the operation is queued and before it is performed. This change allows other operations to run in other sessions in the meantime, removing one of the major iSCSI bottlenecks for us. To prevent the session from being used after the destruction request, we remove it immediately from the sesslist. This simplifies the locking required during the asynchronous removal.

Fixes the occasional adapter panic when sg_reset is issued with -d, -t, -b and -H flags. Removal of command type HBA_IU_TYPE_SCSI_TM_REQ in aac_hba_send since iu_type, request_id and fib_flags are not populated. Device and target reset handlers are made to send TMF commands only when reset_state is 0. Link: https://lore.kernel.org/r/1581553771-25796-1-git-send-email-Sagar.Biradar@microchip.comReviewed-by:

When an SVC node goes down as part of a node reboot, its WWPNs are moved to the remaining node. When the node is back online, its WWPNs are moved back. The result is that the WWPN moves from one NPort_ID to another, then back again. The ibmvfc driver was forcing the old port to be removed, but not sending an implicit logout. When the WWPN showed up at the new location, the PLOGI failed as there was already a login established for the old scsi id. The patch below fixes this by ensuring we always send an implicit logout for any scsi id associated with an rport prior to calling fc_remote_port_delete.

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

The current behavior of the SCSI core is to clear driver-private data before preparing a request for submission to the SCSI LLD. Make it possible for SCSI LLDs to disable clearing of driver-private data. These hooks will be used by a later patch, namely "scsi: ufs: Let the SCSI core allocate per-command UFS data".
