Date: Tue, 6 May 2008 13:35:31 +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 2] UBIFS - new flash file system Hello, here is the second round of UBIFS submission. Please, refer the following URL if you are not familiar what is UBIFS about: http://kerneltrap.org/mailarchive/linux-kernel/2008/3/27/1273514 Additionally, there is a excellent introductional LWN article written by Jonathan Corbet: http://lwn.net/Articles/276025/ (thanks Jonathan). We've addressed most of the requests from the first round and the following is a rough change log: * 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) Besides, several bugs were fixed both in UBIFS and mkfs.ubifs. The on-flash format has also been changed because of the inode time-stamp format changes (milliseconds were added). We've got few users outside of Nokia who seem to be happy with UBIFS and utilize it. There were some positive feed-backs from the community, e.g. http://kerneltrap.org/mailarchive/linux-kernel/2008/4/18/1466334 (thanks Thomas). We kindly ask for more review and feed-back. We'd also like to get into Andrew's mm tree.
