[PATCH 18/30] block: pass gfp_mask and flags to sb_issue_discard
From: Tejun Heo <tj@kernel.org>
Date: 2010-08-25 15:54:07
Also in:
linux-fsdevel, linux-ide, linux-scsi, lkml
Subsystem:
block layer, ext4 file system, filesystems (vfs and infrastructure), the rest, vfat/fat/msdos filesystem · Maintainers:
Jens Axboe, "Theodore Ts'o", Alexander Viro, Christian Brauner, Linus Torvalds, OGAWA Hirofumi
From: Christoph Hellwig <hch@infradead.org> We'll need to get rid of the BLKDEV_IFL_BARRIER flag, and to facilitate that and to make the interface less confusing pass all flags explicitly.
