Date: Mon, 26 May 2008 17:05:14 +0300 From: Artem Bityutskiy <Artem.Bityutskiy@...ia.com> To: LKML <linux-kernel@...r.kernel.org> Cc: Adrian Hunter <ext-adrian.hunter@...ia.com>, "Artem Bityutskiy" <Artem.Bityutskiy@...ia.com> Subject: [PATCH take 3] UBIFS - new flash file system Hello, here is the third round of UBIFS submission. If you are not aware what UBIFS is about, please refer Jonathan Corbet's article: http://lwn.net/Articles/276025/ Also, please refer the second and the first UBIFS submissions which contain short UBIFS description and URLs. second: http://marc.info/?l=linux-kernel&m=121006384211288&w=2 first: http://marc.info/?l=linux-kernel&m=120662475821992&w=2 We've addressed most of the requests from the second round: * Requests from Christoph Hellwig's review (may be found here: http://marc.info/?l=linux-kernel&m=121093446502796&w=2). Few things related to the background thread were not done though. Here are explanations why: http://marc.info/?l=linux-kernel&m=121155640026661&w=2 and http://marc.info/?l=linux-kernel&m=121119680522445&w=2 (see end of the mail). Also, we have not changed readdir() implementation so far, but just put a comment that we cannot support NFS at the moment. However, we have an idea how to fix this, but need some comments from the community. We'll send a separate mail describing the problem and the possible solution shortly. Nevertheless, this should not be a blocker. * The 'generic_sync_sb_inodes()' was introduce as it was pointed to by Andrew Morton. * Many build fixes spotted by Andrew Morton. * Get rid of some dead code spotted by Marcin Slusarz. Other news is that UBIFS has been sitting in -mm tree for a couple of weeks already. And of course we have got more bug reports and fixed more bugs since the last submission. Christoph prefers tarballs - here it is: http://www.infradead.org/~dedekind/ubifs/ubifs-08-05-26.tar.bz2 Changes between take 1 and take 2: * Store milliseconds for [mca]time stamps in the inodes, not only seconds (requested by Andi Kleen) * Documentation/filesystems/ubifs.txt has been added (requested by Josh Boyer) * do_div() is not anymore used with 'unsigned long long' values (requested by Andrew Morton) * The amount of debugging-related config options was lessened and module parameters were introduced instead (requested by Pekka Enberg and Christoph Hellwig) * Many assertions were removed (requested by Pekka Enberg) * Some debugging checks like custom memory leak and memory pressure checks were removed (requested by Pekka Enberg) Thank you, Adrian Hunter Artem Bityutskiy P.S.
