Subject: [PATCH] ext3: "nobh" writeback support for filesystems blocksize < pagesize
X-Git-Tag: v2.6.17-rc1~587

[PATCH] ext3: "nobh" writeback support for filesystems blocksize < pagesize

There is no valid reason why we can't support "nobh" option for filesystems
with blocksize != PAGESIZE.

This patch lets them use "nobh" option for writeback mode for blocksize <
pagesize.
