...he difference between regular memory-cleansing writeback and sync-for-data-integrity purposes. (These two operations are really quite distinct, and the kernel has got it wrong for ages. Even now, kupdate is running filemap_fdatawait() quite needlessly) In the early days, ext3 would assume that a write_super() call meant "sync". That worked OK. But that slowed down the kupdate function - it doesn't need to wait on the writeout. So we took the `wait' out of ext3_write_super(). And that worked OK too, because the VFS would later write back all the dirty data for us. But then an u...

There are three patches at http://www.zip.com.au/~akpm/linux/patches/2.4/2.4.20/ sync_fs.patch: Fix the ext3 data=journal data-loss-on-unmount bug sync_fs-fix.patch: Fix sync_fs.patch to not deadlock the fs when running `mount -o remount' against a heavily loaded filesystem. ext3-use-after-free.patch Fix a use-after-free bug which can cause memory corruption if the filesystem runs

Hello Andrew, I patched 2.4.20 with your patch found out on http://lwn.net/Articles/17447/ and I have a big problem with: once server is booted on 2.4.20 with your patch, when I want to reboot with /sbin/reboot, server makes a Segmentation fault and it crashs. I tested it on 50-60 servers and it is the same problem. I tested kernel 2.4.20 without your patch: no problem. # uname -a Linux XXXXXX

Hi Andrew, The patch below addresses the problem we were talking about earlier where ext3_writepage ends up accessing the inode after the page lock has been dropped (and hence at a point where it is possible for the inode to have been reclaimed.) Tested minimally (it builds and boots.) It makes ext3_journal_stop take an sb, not an inode, as its final parameter. It also sets

Hi, The following patches comprise the bulk of Ocfs2 updates for the 2.6.30 merge window. Aside from larger, more involved fixes, we're adding the following features, which I will describe in the order their patches are mailed. Sunil's exported some more state to our debugfs files, and consolidated some other aspects of our debugfs infrastructure. This will further aid us in debugging
