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.

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

generic_write_checks() expects count to be initialized to the size of the write. Writes to files open with O_DIRECT|O_LARGEFILE write 0 bytes because count in uninitialized.

when we fall back to buffered write from direct write, we call __generic_file_aio_write but that will end up doing direct write even we are only prepared to do buffered write because the file has O_DIRECT flag set.

Hi, We have Ubuntu 14.04.3 server and Samba 4.1.6-Ubuntu. Windows and Mac Os X clients connect this server. Some Os X users sometimes report "error code -43" when file copying to server.

Hi everyone, I want to modify two base R functions 'parse' and 'deparse' immediately after R has started, so I added some code in the file 'Rprofile.site' under the 'etc' directory. Here is a simple example: parse=function(...){ base::parse(...) } I'll get an error when I start R as follows: Error: cannot change value of locked binding for

We''ve run into this before and, in this particular project, I''m positive we had a hack somewhere to get AR to work but it seems to have gone missing and I''m not finding any hints in git history or Google. Any call to an AR.create will trigger it. Seems like a strategically placed require or include did the trick but I''m probably misremembering. The offending

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.

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

Folks- First, let me submit a disclaimer... I know 1.3.12 is unsupported. However, since icecast2 isn't officially released, I'm abit SOL anyways, so I'm currently trying to debug it and will release a patch when I'm done. (Which I'm doing since the code is GPL and I want to contribute... if no one cares, let me know and I'll stop updating the list with what i find)

Ah, I've got it now. >From `?base:bindenv` comes > " The namespace environments of packages with namespaces are locked when loaded." A locked environment > " prevents adding or removing variable bindings from the environment. Changing the value of a variable is still possible unless the binding has been locked" A bit of experimentation shows that as well as

Currently, default behavior of O_DIRECT writes was allowing concurrent writing among nodes, no cluster coherency guaranteed (no EX locks was taken), it hurts buffered reads on other nodes by reading stale data from cache. The new mount option introduce a chance to choose two different behaviors for O_DIRECT writes: * coherency=full, as the default value, will disallow concurrent

Hello, tl;dr: it seems like fsck fails to notice when the block device disappears from under it. I have the following setup: * external USB disk * a partition with LUKS in it * ext4 filesystem inside the LUKS block device While doing backups to it I noticed that after some time backups would fail with an error (failed to write, ). In the following log I'm attaching the disk, enabling LUKS

Hello all, For the past couple of weeks I have been spending some time debugging a couple of issues I was having with Mongrel when I put load on it. I have seen two distinct issues: 1. Mongrel stopped responding as if in an endless loop. 2. Mongrel crashed when severely loaded. I believe to have resolved these two issues and have attached patches which shows the resolution (simple as it is).

Hi, Is the http://xenbits.xensource.com/linux-2.6-xen.hg tree still being updated? if not, what''s the preferred Linux tree to track that has all of the Xen bits?
