Date: Wed, 06 Dec 2006 20:41:23 -0800 From: akpm@...l.org To: torvalds@...l.org Cc: akpm@...l.org, hugh@...itas.com, cmm@...ibm.com, linux-ext4@...r.kernel.org Subject: [patch 344/354] ext3 balloc: reset windowsz when full From: Hugh Dickins <hugh@...itas.com> ext3_new_blocks should reset the reservation window size to 0 when squeezing the last blocks out of an almost full filesystem, so the retry doesn't skip any groups with less than half that free, reporting ENOSPC too soon.
