Oops trace
Trace taken from /var/log/messages
Reply-To: xin.zhong@intel.com A similar bug has been reported by Kenneth Lakin [kennethlakin@gmail.com] last week. It's related to my check-in (git commit 914ee295af418e936ec20a08c1663eaabe4cd07a). I am looking into it now. I found one suspicious code in prepage_pages (fs/btrfs/file.c): start_pos = pos & ~((u64)root->sectorsize - 1); last_pos = ((u64)index + num_pages) << PAGE_CACHE_SHIFT; root->sectorsize is used at first, but PAGE_SIZE is used after it. Do we assume these two values are always the same? -----Original Message----- From: linux-btrfs-owner@vger.kernel.org [mailto:linux-btrfs-owner@vger.kernel.org] On Behalf Of Andrew Morton Sent: Friday, January 07, 2011 5:13 AM To: StMichalke@web.de Cc: bugzilla-daemon@bugzilla.kernel.org; Peter Zijlstra; linux-kernel@vger.kernel.org; linux-btrfs@vger.kernel.org Subject: Re: [Bug 26242] New: BUG: unable to handle kernel NULL pointer dereference at (null) (switched to email.

It's related to my check-in (git commit 914ee295af418e936ec20a08c1663eaabe4cd07a). I am looking into it now. I found one suspicious code in prepage_pages (fs/btrfs/file.c): start_pos = pos & ~((u64)root->sectorsize - 1); last_pos = ((u64)index + num_pages) << PAGE_CACHE_SHIFT; root->sectorsize is used at first, but PAGE_SIZE is used after it.
