From: "Theodore Ts'o" Subject: YET ANOTHER resend of the fiemap patches Date: Sat, 13 Sep 2008 14:47:09 -0400 Message-ID: Cc: Mark Fasheh , linux-ext4@vger.kernel.org To: linux-fsdevel@vger.kernel.org Return-path: Received: from BISCAYNE-ONE-STATION.MIT.EDU ([18.7.7.80]:39389 "EHLO biscayne-one-station.mit.edu" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752285AbYIMSrO (ORCPT ); Sat, 13 Sep 2008 14:47:14 -0400 Sender: linux-ext4-owner@vger.kernel.org List-ID: So the last round of the on-going round-and-round of the FIEMAP patches went to the linux-ext4 mailing list, because of a query there about why these patches had been stalled for so long. This resulted in a private set of e-mails attacking an ext4 developer and putting forward a conspiracy theory that these patches were trying to be snuck in, despite the fact that they have been sent on linux-fsdevel at least 4 times already. Mark has at this point I believe answered all of Christoph Hellwig's demands, and put forward a request to Andrew Morton to include them in -mm (minus the ext4 patch, since the version he had no longer compiled). As of this writing, Andrew has not put them into -mm, I suspect because he perceives there is still controversies around these patches, despite the fact that most of the e-mails and time wasted has been over individual bitflags and other really tiny nit-picky details. So I am re-sending these patches out for review on linux-fsdevel. The first three patches are taken from Mark's fiemap branch on the ocfs2 branch. The last patch is an updated ext4 patch from the ext4 patch queue, which is provided so that folks can see that the fiemap patches work just fine on ext4. Given that filesystem designers seem to love nit-picking tiny details, and I am personally starting to lose patience, if the fiemap patches stalls any further, my plan is to take a page from the XFS playbook and simply take the ext4-fiemap patch and implement an ext4-specific ioctl. If and when the linux-fsdevel community manages come to consensus on the fiemap patches, whether it happens in 2.6.28 or Linux 2.6.87, it will be easy enough to wire the ext4 support to the generic fiemap ioctl.
