similar to: [PATCH] ocfs2: Update atime in splice read if necessary.

Provide a splice_read stub for ocfs2. This emits trace lines and does an atime lock/update before calling filemap_splice_read(). Splicing from direct I/O is handled by the caller. A couple of new tracepoints are added for this purpose. Signed-off-by: David Howells <dhowells at redhat.com> cc: Christoph Hellwig <hch at lst.de> cc: Al Viro <viro at zeniv.linux.org.uk> cc: Jens

From: Zach Brown <zab@zabbo.net> ocfs2''s .aio_read and .aio_write methods are changed to take iov_iter and pass it to generic functions. Wrappers are made to pack the iovecs into iters and call these new functions.

Provide a splice_read stub for ocfs2. This emits trace lines and does an atime lock/update before calling filemap_splice_read(). It doesn't do this for around direct_splice_read() as that will call ->read_iter(). A couple of new tracepoints are added for this purpose.

Hi, here comes the next version of OCFS2 lockdep support. I've dropped patches with fixes from the series since they were already merged. As Joel suggested, I've simplified the main patch a bit so that we don't have ifdefs around lock declarations and there are also a few other minor improvements. Honza

Sorry, please pause this patch review. When I was investigating fstest generic failed case 347 361, I found the wake_up() action should move out the 'if()' area. The correct way is calling wake_up() unconditionally.

Hi, the first four patches in this series fix locking problems in OCFS2 quota code (three of them can lead to potential deadlocks). The fifth patch reorders ip_alloc_sem for directories to be acquired before localalloc locks. Mark would you please merge these? The last two patches implement lockdep annotations for OCFS2 cluster locks. We annotate all the cluster locks except for special ones

Hi, I'm trying to compile ocfs2 1.2.6 on a 2.6.21 kernel (with rsbac and pax patches), but I can't get this to work .. In 2.6.20 there was an change in the definition of the INIT_WORK macro (http://lkml.org/lkml/2006/12/5/269) this seems to cause my problems (see below) but even after removing the third parameter of the INIT_WORK calls the compile fails (see second compile failure). Can

Former logic of ocfs2_file_aio_write() was a bit stricky to unlock the rw_lock and i_alloc_sem, by using some private bits in struct 'iocb' to communite with ocfs2_dio_end_io(), it did work before we introduce the patch of supporting 'coherency=full,buffered' option, since rw_lock and i_alloc_sem were never acquired both at the same time, no mattar we doing buffered or direct IO or

?i, I have a cluster with 5 nodes hosting web application. All web servers save log info into shared access.log file. There is awstats log analyzer on the first node. Sometimes this node fails with the following messages (captured on another server) Apr 20 17:31:16 um-be-2 [145813.022112] o2net: connection to node um-fe-1 (num 1) at 192.168.10.10:7777 has been idle for 30.0 seconds, shutting it

i_alloc_sem has always been a bit of an odd "lock". It''s the only remaining rw_semaphore that can be released by a different thread than the one that locked it, and it''s use case in the core direct I/O code is more like a counter given that the writers already have external serialization. This series removes it in favour of a simpler counter scheme, thus getting rid

I'm running a bit late with the e-mail this time around, but I think that's ok since there really isn't any major new features here - the bulk of the Ocfs2 update is bug fixes, or cleanups. The same goes for configfs. The only two things that could be described as features would be: - Sunil has updated Ocfs2 to provide even more live cluster locking information via debugfs. - Joel

Hi, I'm resending this patch series. It's rediffed against linux-next branch of Joel's git tree. The first four patches are obvious fixes of deadlocks in quota code and should go in as soon as possible. The other three patches implement lockdep support for OCFS2 cluster locks. So you can have a look whether the code make sence to you and possibly merge them. They should be NOP when

In ocfs2_file_aio_write, it does ocfs2_rw_lock first and then ocfs2_inode_lock. But if ocfs2_inode_lock failed, it goes to out_sems without unlocking rw lock. This will cause a bug in ocfs2_lock_res_free when testing res->l_ex_holders, which is increased in __ocfs2_cluster_lock and decreased in __ocfs2_cluster_unlock.
