cdrom: reduce stack usage of mmc_ioctl_dvd_read_struct

2008-12-29T07:28:43Z

1. kmalloc 192 bytes in dvd_read_bca (which is inlined into dvd_read_struct) 2. Pass struct packet_command to all dvd_read_* functions. Checkstack output: Before: mmc_ioctl_dvd_read_struct: 280 After: mmc_ioctl_dvd_read_struct: 56 Signed-off-by: Marcin Slusarz Cc: Bartlomiej Zolnierkiewicz Cc: Andrew Morton Cc: Jens Axboe Signed-off-by: Jens Axboe

cdrom: split mmc_ioctl to lower stack usage

Commands needing to be retried require a complete re-initialization.

The test-unit-ready portion of this patch was causing boots to fail on my test machine (as in http://lkml.org/lkml/2008/12/5/161). With this patch in place, the system is booting reliably. Mike Anderson found the same problem in the hp_hw_start_stop code, and I applied the same solution in cdrom_read_cdda_bpc. Signed-off-by: Alan D. Brunelle Cc: Mike Anderson Signed-off-by: Jens Axboe

[PATCH] beginning of methods conversion

2008-10-21T11:47:32Z

To keep the size of changesets sane we split the switch by drivers; to keep the damn thing bisectable we do the following: 1) rename the affected methods, add ones with correct prototypes, make (few) callers handle both. That's this changeset. 2) for each driver convert to new methods. *ALL* drivers are converted in this series. 3) kill the old (renamed) methods. Note that it _is_ a flagday; all in-tree drivers are converted and by the end of this series no trace of old methods remain. The only reason why we do that this way is to keep the damn thing bisectable and allow per-driver debugging if anything goes wrong. New methods: open(bdev, mode) release(disk, mode) ioctl(bdev, mode, cmd, arg) /* Called without BKL */ compat_ioctl(bdev, mode, cmd, arg) locked_ioctl(bdev, mode, cmd, arg) /* Called with BKL, legacy */ Signed-off-by: Al Viro
