drivers: use non-racy method for proc entries creation (2)

block: no need to initialize rq->cmd with blk_get_request

2008-04-29T12:48:55Z

blk_get_request initializes rq->cmd (rq_init does) so the users don't need to do that. The purpose of this patch is to remove sizeof(rq->cmd) and &rq->cmd, as a preparation for large command support, which changes rq->cmd from the static array to a pointer. sizeof(rq->cmd) will not make sense and &rq->cmd won't work.

cdrom: use kmalloced buffers instead of buffers on stack

2008-04-21T07:50:08Z

If cdrom commands are issued to a scsi drive in most cases the buffer will be filled via dma. This leads to bad stack corruption on non coherent platforms, because the buffers are neither cache line aligned nor is the size a multiple of the cache line size. Using kmalloced buffers avoids this. Signed-off-by: Thomas Bogendoerfer Signed-off-by: Jens Axboe

cdrom: make unregister_cdrom() return void

2008-04-21T07:50:08Z

Now unregister_cdrom() always returns 0. Make it return void and update all callers that check the return value. Signed-off-by: Akinobu Mita Cc: Adrian McMenamin Cc: Borislav Petkov Signed-off-by: Jens Axboe

cdrom: use list_head for cdrom_device_info list

2008-04-21T07:50:08Z

Use list_head for cdrom_device_info list instead of opencoded singly list handling. Signed-off-by: Akinobu Mita Signed-off-by: Jens Axboe

cdrom: protect cdrom_device_info list by mutex

2008-04-21T07:50:08Z

This patch protects the list of cdrom_device_info by cdrom_mutex when the file in /proc/sys/dev/cdrom/ is written. Signed-off-by: Akinobu Mita Signed-off-by: Jens Axboe

cdrom: cleanup hardcoded error-code

2008-04-21T07:50:07Z

This patch eliminates hardcoded return value of register_cdrom(). It also changes the return value to -EINVAL. It is more appropriate than -2 (-ENOENT) because it is only happen invalid usage of register_cdrom() by broken cdrom driver. Signed-off-by: Akinobu Mita Signed-off-by: Jens Axboe

cdrom: remove ifdef CONFIG_SYSCTL

2008-04-21T07:50:07Z

This patch removes #ifdef for CONFIG_SYSCTL by defining empty cdrom_sysctl_register and cdrom_sysctl_unregister when CONFIG_SYSCTL is not defined. Signed-off-by: Akinobu Mita Signed-off-by: Jens Axboe
