This patch is a >= v4.1 regression bug-fix where control CDB emulation logic in commit 38b57f82 now expects a se_cmd->se_sess pointer to exist when determining T10-PI support is to be exposed for initiator host ports. To address this bug, go ahead and add locally generated se_cmd descriptors for copy-offload block-copy to it's own stand-alone se_session nexus, while the parent EXTENDED_COPY se_cmd descriptor remains associated with it's originating se_cmd->se_sess nexus. Note a valid se_cmd->se_sess is also required for future support of WRITE_INSERT and READ_STRIP software emulation when submitting backend I/O to se_device that exposes T10-PI suport. Reported-by:

This patch adds an optional fabric driver provided SGL limit that target-core will honor as it's own internal I/O maximum transfer length limit, as exposed by EVPD=0xb0 block limits parameters. This is required for handling cases when host I/O transfer length exceeds the requested EVPD block limits maximum transfer length. The initial user of this logic is qla2xxx, so that we can avoid having to reject I/Os from some legacy FC hosts where EVPD=0xb0 parameters are not honored. When se_cmd payload length exceeds the provided limit in target_check_max_data_sg_nents() code, se_cmd->data_length + se_cmd->prot_length are reset with se_cmd->residual_count plus underflow bit for outgoing TFO response callbacks. It also checks for existing CDB level underflow + overflow and recalculates final residual_count as necessary. Note this patch currently assumes 1:1 mapping of PAGE_SIZE per struct scatterlist entry.

Pull blk-cg updates from Jens Axboe: "A bit later in the cycle, but this has been in the block tree for a a while. This is basically four patchsets from Tejun, that improve our buffered cgroup writeback. It was dependent on the other cgroup changes, but they went in earlier in this cycle. Series 1 is set of 5 patches that has cgroup writeback updates: - bdi_writeback iteration fix which could lead to some wb's being skipped or repeated during e.g. sync under memory pressure. - Simplification of wb work wait mechanism. - Writeback tracepoints updated to report cgroup. Series 2 is is a set of updates for the CFQ cgroup writeback handling: cfq has always charged all async IOs to the root cgroup. It didn't have much choice as writeback didn't know about cgroups and there was no way to tell who to blame for a given writeback IO. writeback finally grew support for cgroups and now tags each writeback IO with the appropriate cgroup to charge it against. This patchset updates cfq so that it follows the blkcg each bio is tagged with. Async cfq_queues are now shared across cfq_group, which is per-cgroup, instead of per-request_queue cfq_data. This makes all IOs follow the weight based IO resource distribution implemented by cfq. - Switched from GFP_ATOMIC to GFP_NOWAIT as suggested by Jeff. - Other misc review points addressed, acks added and rebased. Series 3 is the blkcg policy cleanup patches: This patchset contains assorted cleanups for blkcg_policy methods and blk[c]g_policy_data handling. - alloc/free added for blkg_policy_data. exit dropped. - alloc/free added for blkcg_policy_data. - blk-throttle's async percpu allocation is replaced with direct allocation. - all methods now take blk[c]g_policy_data instead of blkcg_gq or blkcg. And finally, series 4 is a set of patches cleaning up the blkcg stats handling: blkcg's stats have always been somwhat of a mess. This patchset tries to improve the situation a bit. - The following patches added to consolidate blkcg entry point and blkg creation. This is in itself is an improvement and helps colllecting common stats on bio issue. - per-blkg stats now accounted on bio issue rather than request completion so that bio based and request based drivers can behave the same way. The issue was spotted by Vivek. - cfq-iosched implements custom recursive stats and blk-throttle implements custom per-cpu stats. This patchset make blkcg core support both by default. - cfq-iosched and blk-throttle keep track of the same stats multiple times.

Due to some recent changes in drm_helper_probe_single_connector_modes_merge_bits(), old custom modes were not being pruned properly. In current kernels, drm_mode_validate_basic() is called to sanity-check each mode in the list. If the sanity-check passes, the mode's status gets set to to MODE_OK. In older kernels this check was not done, so old custom modes would still have a status of MODE_UNVERIFIED at this point, and would therefore be pruned later in the function. As a result of this new behavior, the list of modes for a device always includes every custom mode ever configured for the device, with the largest one listed first. Since desktop environments usually choose the first preferred mode when a hotplug event is emitted, this had the result of making it very difficult for the user to reduce the size of the display. The qxl driver did implement the mode_valid connector function, but it was empty. In order to restore the old behavior where old custom modes are pruned, we implement a proper mode_valid function for the qxl driver. This function now checks each mode against the last configured custom mode and the list of standard modes. If the mode doesn't match any of these, its status is set to MODE_BAD so that it will be pruned as expected. Signed-off-by:
