Subject: [PATCH v2 0/6] Make blkdev_issue_discard() submit aligned discard requests
Date: Thu, 17 Dec 2015 12:38:55 +0100 [thread overview]
Message-ID: <56729ECF.50906@sandisk.com> (raw)
Users of blkdev_issue_discard(), e.g. blk_ioctl_discard(), expect that
this function generates discard request(s) that satisfy block driver
alignment requirements. Hence modify blk_bio_discard_split() such that
the submitted discard requests are aligned.
Changes compared to v1:
- Moved the code to split discard requests from blkdev_issue_discard()
into blk_bio_discard_split().
The patches in this series are:
0001-block-Introduce-blk_round_sect_down.patch
0002-block-Introduce-bio_add_zero_pages.patch
0003-block-Optimize-__blkdev_issue_zeroout.patch
0004-block-Make-blkdev_issue_discard-submit-aligned-disca.patch
0005-brd-Split-bio-if-needed.patch
0006-brd-Accept-non-aligned-discard-requests-with-size-ze.patch
