* block: push down BKL into .locked_ioctlArnd Bergmann2010-08-071-2/+15
| | | | | | | | | | | As a preparation for the removal of the big kernel lock in the block layer, this removes the BKL from the common ioctl handling code, moving it into every single driver still using it.

* floppy: use warning macrosStephen Hemminger2010-08-071-16/+11
| | | | | | | | | | Convert assertions to use WARN(). There are several error checks in the code for things that should never happen. Convert them to standard warnings so kerneloops.org will see them.

* block: Rename blk_queue_max_sectors to blk_queue_max_hw_sectorsMartin K. Petersen2010-02-261-1/+1
| | | | | | | | | | | | | The block layer calling convention is blk_queue_<limit name>. blk_queue_max_sectors predates this practice, leading to some confusion. Rename the function to appropriately reflect that its intended use is to set max_hw_sectors. Also introduce a temporary wrapper for backwards compability. This can be removed after the merge window is closed. Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
* floppy: Add an extra bound check on ioctl argumentsArjan van de Ven2009-12-151-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | gcc is not convinced that the floppy.c ioctl has sufficient bound checks: In function `copy_from_user', inlined from `fd_copyin' at drivers/block/floppy.c:3080, inlined from `fd_ioctl' at drivers/block/floppy.c:3503: arch/x86/include/asm/uaccess_32.h:211: warning: call to `copy_from_user_overflow' declared with attribute warning: copy_from_user buffer size is not provably correct And frankly, as a human I have a hard time proving the same more or less (the size comes from the ioctl argument. humpf. maybe. the code isn't very nice) This patch adds an explicit check to make 100% sure it's safe, better than finding out later that there indeed was a gap.
