sx8: use real time for the command seconds

2015-12-23T15:42:59+00:00

Commit 8182503df1ba used monotonic time, but if the adapter is using the seconds for logging entries, then we'll get duplicate entries if the system is rebooted. Use real time instead.

block: sx8.c: Replace timeval with ktime_t

2015-12-22T17:19:46+00:00

32-bit systems using 'struct timeval' will break in the year 2038, in order to avoid that replace the code with more appropriate types. This patch replaces timeval with 64 bit ktime_t which is y2038 safe. Since st->timestamp is only interested in seconds, directly using time64_t here. Function ktime_get_seconds is used since it uses monotonic instead of real time and thus will not cause overflow. Signed-off-by: Shraddha Barke Signed-off-by: Jens Axboe

block,scsi: fixup blk_get_request dead queue scenarios

2014-08-28T16:03:46+00:00

The blk_get_request function may fail in low-memory conditions or during device removal (even if __GFP_WAIT is set). To distinguish between these errors, modify the blk_get_request call stack to return the appropriate ERR_PTR. Verify that all callers check the return status and consider IS_ERR instead of a simple NULL pointer check. For consistency, make a similar change to the blk_mq_alloc_request leg of blk_get_request. It may fail if the queue is dead, or the caller was unwilling to wait.

drivers/block/sx8.c: remove unnecessary pci_set_drvdata()

2014-01-22T04:16:56+00:00

The driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL. Signed-off-by: Jingoo Han Cc: Jens Axboe Signed-off-by: Andrew Morton Signed-off-by: Jens Axboe

drivers/block/sx8.c: use module_pci_driver()

Use module_pci_driver() macro which makes the code smaller and simpler. Signed-off-by: Jingoo Han Cc: Jens Axboe Signed-off-by: Andrew Morton Signed-off-by: Jens Axboe

block, sx8: fix pointer math issue getting fw version

"mem" is type u8. We need parenthesis here or it screws up the pointer math probably leading to an oops. Signed-off-by: Dan Carpenter Cc: stable@kernel.org Acked-by: Jeff Garzik Signed-off-by: Jens Axboe

block, sx8: kill blk_insert_request()

2011-12-13T23:33:37+00:00

The only user left for blk_insert_request() is sx8 and it can be trivially switched to use blk_execute_rq_nowait() - special requests aren't included in io stat and sx8 doesn't use block layer tagging. Switch sx8 and kill blk_insert_requeset(). This patch doesn't introduce any functional difference. Only compile tested. Signed-off-by: Tejun Heo Acked-by: Jeff Garzik Signed-off-by: Jens Axboe

block: Consolidate phys_segment and hw_segment limits

Except for SCSI no device drivers distinguish between physical and hardware segment limits. Consolidate the two into a single segment limit. Signed-off-by: Martin K. Petersen Signed-off-by: Jens Axboe

block: make PCI device id constant

2010-01-11T13:31:26+00:00

The id_table field of the struct pci_driver is constant in so it is worth to make the initialization data also constant.
