Subject: [PATCH 0/3] Fix more NFS readdir regressions
Date: Tue, 30 Nov 2010 22:47:11 -0500 [thread overview]
Message-ID: <1291175234-23824-1-git-send-email-Trond.Myklebust@netapp.com> (raw)
In-Reply-To: <AANLkTimg+4EYfYnKqNsoOpvCcDs+Pb=FB+arb4NvFpx_@mail.gmail.com>
OK. The first patch in this series fixes the regression reported by
Nick Bowler when I apply it to my setup.
The 2 remaining patches are needed in order to ensure that the
VM doesn't free the readdir page cache page while we're trying to
read from it, and to ensure that we don't leak memory...
Linus, please don't apply these patches quite yet. I'd like to continue
tests for a couple more days before I send you the pull request.
Cheers
Trond
