similar to: nasty ext3 problem

This patch fixes the data loss which can occur when unmounting a data=journal ext3 filesystem. The core problem is that the VFS doesn't tell the filesystem enough about what is happening. ext3 _needs_ to know the 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

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

Greetings all, I have a question regarding the fsync data corruption bug that was introduced in 2.4.20 when using data=journal. I have patched the 2.4.20 kernel with the 3 sync patches available from zip.com.au, and I am wondering if with these patches the "bug" still exists: sync_fs.patch sync_fs-fix.patch sync_fs-fix-2.patch In addition the following two patches have also

Hi Chris- Here''s a simpler version of the patch that drops the unrelated sync_fs stuff. thanks- sage The ''flushoncommit'' mount option forces any data dirtied by a write in a prior transaction to commit as part of the current commit. This makes the committed state a fully consistent view of the file system from the application''s perspective (i.e., it

Hi there, I'm using xen-3.0.2.2-86.1_rhel4.1 on a Redhat AS 4 update 1 for i386.

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

oh, I am using: $ quota -V Quota utilities version 3.13.

In commit ea455f8ab68338ba69f5d3362b342c115bea8e13, we move the dentry lock put process into ocfs2_wq. This is OK for most case, but as for umount, it lead to at least 2 bugs. See http://oss.oracle.com/bugzilla/show_bug.cgi?id=1133 and http://oss.oracle.com/bugzilla/show_bug.cgi?id=1135. And it happens easily if we have opened a lot of inodes. For 1135, the reason is that during umount will call
