* block: unexport DISK_EVENT_MEDIA_CHANGE for legacy/fringe driversTejun Heo2011-04-211-1/+0
| | | | | | | | | | | | | | | In-kernel disk event polling doesn't matter for legacy/fringe drivers and may lead to infinite event loop if ->check_events() implementation generates events on level condition instead of edge. Now that block layer supports suppressing exporting unlisted events, simply leaving disk->events cleared allows these drivers to keep the internal revalidation behavior intact while avoiding weird interactions with userland event handler.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * scsi/i2o: restore ioctl changesArnd Bergmann2010-08-071-5/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
