From: Neil Brown Date: Tue, 23 Oct 2007 21:09:13 +0000 (-0400) Subject: NFS: Fix for bug in handling of errors for O_DIRECT writes X-Git-Tag: v2.6.24-rc1~17 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=432409eebcdec38ff6fa949f097b5438d588faa5;p=linux-2.6 NFS: Fix for bug in handling of errors for O_DIRECT writes Commit eda3cef8dd2b83875affe82595db9d0c278879b2 ("NFS: Fix error handling in nfs_direct_write_result()") ensured that if a WRITE returns an error, then data->res.verf->committed is not tested (as it is not initialised). Then commit 60fa3f769f7651a60125a0f44e3ffe3246d7cf39 ("NFS: Fix two bugs in the O_DIRECT write code") inadvertently reverted this while fixing other problems. So move the test so that we never examine ->committed in an error case, and fix a speeling error while we are there.
