Subject: [PATCH] xfs: fix the extent count when allocating an new indirection array entry
Date: Sat, 21 Sep 2013 22:38:31 +0800 [thread overview]
Message-ID: <523DAF67.9070206@oracle.com> (raw)
From: Jie Liu <jeff.liu@oracle.com>
At xfs_iext_add(), if extent(s) are being appended to the last
page in the indirection array and the new extent(s) don't fit
in the page, the number of extents(erp->er_extcount) in a new
allocated entry should be the minimum value between count and
XFS_LINEAR_EXTS, instead of count.
