Subject: Re: linux-2.6-block/for-next: Removal of BLKDEV_IFL_BARRIER and BLKDEV_IFL_WAIT

Commit 4bcf787b503fa96c5a2f529ce15807dc670853ed from ext4/next [1]:
"Add helper function for blkdev_issue_zeroout (sb_issue_discard)"

...lead to some rework of my initial patch, so here is v2 attached.

As blkdev_issue_zeroout() has no more "flags", this has to be
considered also in sb_issue_zeroout() and also in my v2 patch.

[ block/blk-lib.c ]
...
int blkdev_issue_zeroout(struct block_device *bdev, sector_t sector,
                        sector_t nr_sects, gfp_t gfp_mask)
...

Looks like this is compiling w/o errors in fs/ext4 tree.
