...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 unrelated optimisation to the truncate path caused that to not work any more, and we were exposed. This patch adds a new super_block operation `sync_fs', whose mandate is to "sync the filesystem" for data-integrity purposes. ie: it is a synchronous writeout, whereas write_super is an asynchronous flush. It is a minimal fix. Really all the `sync' code in the VFS needs a rethink. It is _very_ ext2-centric, an...

Hi, This is the second batch of Ocfs2 patches intended for the merge window. The 1st batch were sent out previously: http://lkml.org/lkml/2008/12/19/280 The bulk of this set is comprised of Jan Kara's patches to add quota support to Ocfs2. Many of the quota patches are to generic code, which I carried to make merging of the Ocfs2 support easier. All of the non-ocfs2 patches should have

Hi all, This patch set adds batched discard support to ocfs2. Please check. Thanks. Regards, Tao

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

Hello, the following series of patches fixes some issues with OCFS2 quotas. The first patch modifies VFS quota locking, the next patch uses the fact to simplify OCFS2 quota locking and solves a few deadlock issues. The third and the fourth patches fix another possible deadlocks in OCFS2 quota code and the last patch is a minor cleanup. Honza

Hello, the following patch series implements quotas for OCFS2. The patch series is based on: git://git.kernel.org/pub/scm/linux/kernel/git/mfasheh/ocfs2.git linux-next I've adressed Joel's comments, also node recovery is now fully working and I've fixed a few issues I found during my testing. So I'm currently not aware of any bugs. Please review, test, comment. Thanks.

Hi, All, When mount ocfs2 with option usrquota and grpquota, we will see below message: (mount.ocfs2,9434,1):ocfs2_global_read_info:403 ERROR: status = 24 (mount.ocfs2,9434,3):ocfs2_global_read_info:403 ERROR: status = 24 But actually this should not be a error. In ocfs2_global_read_info, if read_quota() succeed, status is the size of the struct ocfs2_global_disk_dqinfo, only when it is not

Hi, here is the second version of OCFS2 quota fixes with Joel's comments fixed. Also I've added a patch defining counts of credits for quota operations as Joel asked. Honza
