From: Andrew Morton <akpm@zip.com.au> To: lkml <linux-kernel@vger.kernel.org>, "ext3-users@redhat.com" <ext3-users@redhat.com> Subject: ext3-2.4-0.9.9 Date: Fri, 07 Sep 2001 11:34:46 -0700 Patches against 2.4.10-pre4 and 2.4.9-ac9 are at http://www.uow.edu.au/~andrewm/linux/ext3/ It's a fairly large change. The most significant parts are * the inclusion of Stephen's error-handling work, which is designed to remount the fs read-only in the presence of software and hardware errors, rather than forcing a panic. * Stephen's fix for the journal_revoke assertion failure which three people have reported. There have been two reports of a possible interaction problem with vfat where a readdir on the vfat mountpoint returns ENOTDIR when ext3 is present in the kernel. This has proved elusive and in fact has been observed on systems where ext3 was never used. It is probably a vfat bug. At the above website there is also a patch from Ted Ts'o which will provide significant speedups for accessing large directories. Ted's equivalent patch for ext2 has already been incorporated into the official kernel(s). If possible, please test Ted's patch on top of ext3 0.9.9. Detailed changelog: 0.9.7 ----- - Merge in a large batch of changes to allow ext3 to recover gracefully from fatal errors. If the fs is set to remount-readonly on error, then we should still be able to unwind cleanly and unmount the filesystem. - Performance: don't write superblocks synchronously. This reduces a bottleneck in the VM. Load the ext3 module with the parameter "do_sync_supers=1" to restore the previous behaviour. - Performance: don't force a new transaction every time we sync (should prevent the writes previously happening every 5 seconds, allowing laptop drives to spin down again.) 0.9.8 ----- - Fix an NFS oops when doing a local delete on an active, nfs-exported file. - Add proper log levels to a lot of kernel warnings when mounting a bad filesystem or a fs with errors - Make sure we set the error flag both in the journal and fs superblocks on error (unless we're doing panic-on-error) 0.9.9 ----- - Fix the buffer-already-revoked assertion failure by looking up an aliased buffercache buffer and clearing the revoke bits in there as well as in the journalled data buffer. - Reorganise page truncation code so we don't take the address of block_flushpage(). This is to simplify merging with Andrea's O_DIRECT patch, which turns block_flushpage() into a macro. - - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
