When creating images for virtual machines it might be required to use a different physical blocksize (eg 4k for S/390 DASD). This patchset extends the current LOOP_SET_STATUS64 ioctl to set the logical and physical blocksize by re-using the existing 'init' fields, which are currently unused. As usual, comments and reviews are welcome. Hannes Reinecke (4): loop: Enable correct physical blocksize loop: Remove unused 'bdev' argument from loop_set_capacity loop: Add 'lo_logical_blocksize' loop: Pass logical blocksize in 'lo_init[0]' ioctl field drivers/block/loop.c | 35 ++++++++++++++++++++++++++++++----- drivers/block/loop.h | 1 + include/uapi/linux/loop.h | 1 + 3 files changed, 32 insertions(+), 5 deletions(-) -- 1.8.5.2 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
