Subject: [patch 344/354] ext3 balloc: reset windowsz when full
Date: Wed, 06 Dec 2006 20:41:23 -0800 [thread overview]
Message-ID: <200612070441.kB74fNgo030352@shell0.pdx.osdl.net> (raw)
From: Hugh Dickins <hugh@veritas.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.
