* block: add and use scsi_blk_cmd_ioctlPaolo Bonzini2012-01-251-2/+1
| | | | | | | | | | | | | | | | | commit 577ebb374c78314ac4617242f509e2f5e7156649 upstream. Introduce a wrapper around scsi_cmd_ioctl that takes a block device. The function will then be enhanced to detect partition block devices and, in that case, subject the ioctls to whitelisting.

* block: autoconvert trivial BKL users to private mutexArnd Bergmann2010-10-051-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The block device drivers have all gained new lock_kernel calls from a recent pushdown, and some of the drivers were already using the BKL before. This turns the BKL into a set of per-driver mutexes. Still need to check whether this is safe to do. 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>
* block: push down BKL into .locked_ioctlArnd Bergmann2010-08-071-3/+9
| | | | | | | | | | | 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.

* ide-atapi: remove pc->bufBorislav Petkov2009-05-151-1/+0
| | | | | | | | | Now after all users of pc->buf have been converted, remove the 64B buffer embedded in each packet command. There should be no functional change resulting from this patch. Signed-off-by: Borislav Petkov <petkovbb@gmail.com>

* ide-atapi: add a buffer-arg to ide_queue_pc_tailBorislav Petkov2009-05-151-8/+8
| | | | | | | | | | | | | | This is in preparation of removing ide_atapi_pc. Expose the buffer as an argument to ide_queue_pc_tail with later replacing it with local buffer or even kmalloc'ed one if needed due to stack usage constraints. Also, add the possibility of passing a NULL-ptr buffer for cmds which don't transfer data besides the cdb. While at it, switch to local buffer in idetape_get_mode_sense_results(). There should be no functional change resulting from this patch. Signed-off-by: Borislav Petkov <petkovbb@gmail.com>

* ide: decrease size of ->pc_buf field in struct ide_atapi_pcBartlomiej Zolnierkiewicz2009-03-311-1/+4
| | | | | | | | | | struct ide_atapi_pc is often allocated on the stack and size of ->pc_buf size is 256 bytes. However since only ide_floppy_create_read_capacity_cmd() and idetape_create_inquiry_cmd() require such size allocate buffers for these pc-s explicitely and decrease ->pc_buf size to 64 bytes.

* ide-floppy: allocate only toplevel packet commandsLinus Torvalds2009-01-021-28/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the top-level function just allocate a single pc entry, and then pass it down as a pointer to all the helper functions that also need one of those "struct ide_atapi_pc" things. As far as I can tell, the use of these things never overlaps each other, BUT I DID NOT CHECK VERY CLOSELY! So I'm not guaranteeing this is correct, and I don't have the hardware. It would be good for somebody who knows the code more, and has the hardware, could please test this? With this, ide-floppy still has fairly big stack usage, but instead of idefloppy_ioctl [vmlinux]: 1208 ide_floppy_get_capacity [vmlinux]: 872 idefloppy_release [vmlinux]: 408 idefloppy_open [vmlinux]: 408 where those two first ones are at the very top of the list of stack users for me, it's now ide_floppy_get_capacity [vmlinux]: 404 ide_floppy_ioctl [vmlinux]: 364 ie they are still high, but they are no longer at the top. Borislav: Since ide_floppy_get_capacity is passed as a function pointer to other parts of the kernel (e.g., block layer) we need that ide_atapi_pc to be created on stack. Also, redid stack users numbers above. The two functions missing from Linus' original 'make stackusage' output are due to ide being rewritten/reorganized atm.
