2012-10-09[SCSI] storvsc: Account for in-transit packets in the RESET pathK. Y. Srinivasan
Properly account for I/O in transit before returning from the RESET call. In the absense of this patch, we could have a situation where the host may respond to a command that was issued prior to the issuance of the RESET command at some arbitrary time after responding to the RESET command. Currently, the host does not do anything with the RESET command. Signed-off-by: K. Y.

2012-04-25[SCSI] storvsc: Properly handle errors from the hostK. Y. Srinivasan
Hyper-V cannot process some commands like ATA_12 and ATA_16. It also returns a very generic error when this happens (SRB_STATUS_ERROR). Most of the time we treat SRB_STATUS_ERROR as DID_TARGET_FAILURE which causes error handler retry, but in the case of pass through commands, they'll never succeed (and the error handler will offline the device), so put a discriminating block in the command completion routing and send the SRB_STATUS_ERROR upwards with DID_PASSTHROUGH for commands we know should not be retried.

2012-03-21Merge branch 'kmap_atomic' of git://github.com/congwang/linuxLinus Torvalds
Pull kmap_atomic cleanup from Cong Wang. It's been in -next for a long time, and it gets rid of the (no longer used) second argument to k[un]map_atomic(). Fix up a few trivial conflicts in various drivers, and do an "evil merge" to catch some new uses that have come in since Cong's tree. * 'kmap_atomic' of git://github.com/congwang/linux: (59 commits) feature-removal-schedule.txt: schedule the deprecated form of kmap_atomic() for removal highmem: kill all __kmap_atomic() [swarren@nvidia.com: highmem: Fix ARM build break due to __kmap_atomic rename] drbd: remove the second argument of k[un]map_atomic() zcache: remove the second argument of k[un]map_atomic() gma500: remove the second argument of k[un]map_atomic() dm: remove the second argument of k[un]map_atomic() tomoyo: remove the second argument of k[un]map_atomic() sunrpc: remove the second argument of k[un]map_atomic() rds: remove the second argument of k[un]map_atomic() net: remove the second argument of k[un]map_atomic() mm: remove the second argument of k[un]map_atomic() lib: remove the second argument of k[un]map_atomic() power: remove the second argument of k[un]map_atomic() kdb: remove the second argument of k[un]map_atomic() udf: remove the second argument of k[un]map_atomic() ubifs: remove the second argument of k[un]map_atomic() squashfs: remove the second argument of k[un]map_atomic() reiserfs: remove the second argument of k[un]map_atomic() ocfs2: remove the second argument of k[un]map_atomic() ntfs: remove the second argument of k[un]map_atomic() ...
2012-02-13Staging: hv: storvsc: Move the storage driver out of the staging areaK. Y. Srinivasan
The storage driver (storvsc_drv.c) handles all block storage devices assigned to Linux guests hosted on Hyper-V. This driver has been in the staging tree for a while and this patch moves it out of the staging area. James was willing to apply this patch during the 3.3-rc phase and a decision was taken to defer this to 3.4 since Greg had queued up a bunch of storvsc patches for 3.4. Now that Greg has applied all of the pending storvsc patches, I am sending this patch to move this driver out of staging. Based on James' recommendation, this patch gets rid of the unneeded files in the staging/hv directory. Signed-off-by: K. Y.
