| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bus reset is not required for SAS Controller. It is valid for mptspi and mptfc, but for mptsas it is not required.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a branch at the end of this function that is supposed to normalize the return value with what the mid-layer expects. In this one case, we get it wrong. Also increase the verbosity of the INFO level printk at the end of mptscsih_abort to include the actual return value and the scmd->serial_number. The reason being success or failure is actually determined by the state of the internal tag list when a TMF is issued, and not the return value of the TMF cmd. The serial_number is also used in this decision, thus it's useful to know for debugging purposes. Cc: stable@kernel.org Reported-by: Peter M.

| * SCSI host lock push-downJeff Garzik2010-11-164-7/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the mid-layer's ->queuecommand() invocation from being locked with the host lock to being unlocked to facilitate speeding up the critical path for drivers who don't need this lock taken anyway. The patch below presents a simple SCSI host lock push-down as an equivalent transformation. No locking or other behavior should change with this patch. All existing bugs and locking orders are preserved. Additionally, add one parameter to queuecommand, struct Scsi_Host * and remove one parameter from queuecommand, void (*done)(struct scsi_cmnd *) Scsi_Host* is a convenient pointer that most host drivers need anyway, and 'done' is redundant to struct scsi_cmnd->scsi_done. Minimal code disturbance was attempted with this change. Most drivers needed only two one-line modifications for their host lock push-down.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All these files use the big kernel lock in a trivial way to serialize their private file operations, typically resulting from an earlier semi-automatic pushdown from VFS. None of these drivers appears to want to lock against other code, and they all use the BKL as the top-level lock in their file operations, meaning that there is no lock-order inversion problem. Consequently, we can remove the BKL completely, replacing it with a per-file mutex in every case. Using a scripted approach means we can avoid typos. file=$1 name=$2 if grep -q lock_kernel ${file} ; then if grep -q 'include.*linux.mutex.h' ${file} ; then sed -i '/include.*<linux\/smp_lock.h>/d' ${file} else sed -i 's/include.*<linux\/smp_lock.h>.*$/include <linux\/mutex.h>/g' ${file} fi sed -i ${file} \ -e "/^#include.*linux.mutex.h/,$ { 1,/^\(static\|int\|long\)/ { /^\(static\|int\|long\)/istatic DEFINE_MUTEX(${name}_mutex); } }" \ -e "s/\(un\)*lock_kernel\>[ ]*()/mutex_\1lock(\&${name}_mutex)/g" \ -e '/[ ]*cycle_kernel_lock();/d' else sed -i -e '/include.*\<smp_lock.h\>/d' ${file} \ -e '/cycle_kernel_lock()/d' fi Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: linux-scsi@vger.kernel.org Cc: "James E.J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This restores the changes from "scsi/i2o_block: cleanup ioctl handling", which accidentally got reverted. Origignal changelog: This fixes the ioctl function of the i2o_block driver, which has multiple problems: * The BLKI2OSRSTRAT and BLKI2OSWSTRAT commands always return -ENOTTY on success, where they should return 0. * Support for 32 bit compat is missing * The driver should use the .ioctl function and because .locked_ioctl is going away. The use of the big kernel lock remains for now, but gets made explictit in the ioctl function. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
| * block: push down BKL into .open and .releaseArnd Bergmann2010-08-071-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The open and release block_device_operations are currently called with the BKL held. In order to change that, we must first make sure that all drivers that currently rely on this have no regressions. This blindly pushes the BKL into all .open and .release operations for all block drivers to prepare for the next step. The drivers can subsequently replace the BKL with their own locks or remove it completely when it can be shown that it is not needed. The functions blkdev_get and blkdev_put are the only remaining users of the big kernel lock in the block layer, besides a few uses in the ioctl code, none of which need to serialize with blkdev_{get,put}. Most of these two functions is also under the protection of bdev->bd_mutex, including the actual calls to ->open and ->release, and the common code does not access any global data structures that need the BKL.

Before device get deleted from OS, Device may go OFFLINE as part of error handling kicked off triggered from multipathing driver. Above condition hits more frequently if device missing delay timer (which is LSI specific firmware parameter) is non zero value. root cause of this issue is Error handling thread is getting kicked off for device which is not really present(in transient state of deleting). This patch has solution for this issue. driver is now using eh_timed_out callback. See below. mptsas_transport_template->eh_timed_out = mptsas_eh_timed_out Using mptsas_eh_timed_out function, driver can decide weather vdevice is under Device missing delay or deleting state. for either of those cases, there is BLK_EH_RESET_TIMER return to scsi mid and error handling thread will not be kicked off for that particular scsi command.
