From: Adrian Hunter on 7 Jul 2010 07:20 Hi Add ability to do MMC erase and secure erase operations from userspace, using the BLKDISCARD ioctl and a newly created BLKSECDISCARD ioctl. This is version 4 of these patches. Changes from V3 - rebased on mmotm - added SD/MMC device attribute documentation to 'mmc: Add erase, secure erase, trim and secure trim operations' patch Changes from V2 - move the addition of BLKSECDISCARD to a separate patch and implement it using I/O requests - move the MMC support of secure discard to a separate patch and support the secure discard I/O request Changes from V1 - use discard I/O requests instead of implementing BLKDISCARD in mmc_block - do not validate erase size for MMC erases, instead round to erase size - rename MMC max_erase to pref_erase and expose it through sysfs as preferred_erase_size Adrian Hunter (5): mmc: Add erase, secure erase, trim and secure trim operations mmc_block: Add discard support omap_hsmmc: Add erase capability block: Add secure discard mmc_block: Add support for secure discard Documentation/00-INDEX | 2 + Documentation/mmc/00-INDEX | 4 + Documentation/mmc/mmc-dev-attrs.txt | 56 ++++++ block/blk-core.c | 5 +- block/blk-lib.c | 6 + block/compat_ioctl.c | 1 + block/elevator.c | 6 + block/ioctl.c | 15 +- drivers/mmc/card/block.c | 82 ++++++++- drivers/mmc/card/queue.c | 19 ++- drivers/mmc/core/core.c | 346 +++++++++++++++++++++++++++++++++++ drivers/mmc/core/core.h | 2 + drivers/mmc/core/mmc.c | 47 +++++- drivers/mmc/core/sd.c | 82 ++++++++ drivers/mmc/core/sd_ops.c | 48 +++++ drivers/mmc/core/sd_ops.h | 1 + drivers/mmc/host/omap_hsmmc.c | 13 +- include/linux/bio.h | 2 + include/linux/blkdev.h | 7 +- include/linux/fs.h | 2 + include/linux/mmc/card.h | 19 ++ include/linux/mmc/core.h | 19 ++ include/linux/mmc/host.h | 1 + include/linux/mmc/mmc.h | 26 ++- include/linux/mmc/sd.h | 5 + kernel/trace/blktrace.c | 8 + 26 files changed, 803 insertions(+), 21 deletions(-) create mode 100644 Documentation/mmc/00-INDEX create mode 100644 Documentation/mmc/mmc-dev-attrs.txt Regards Adrian -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
