This patch plugs a race between the downconvert thread and an unlock ast message. Specifically, after the downconvert worker has done its task, the dc thread needs to check whether an unlock ast made the downconvert moot.

David, So here are the two patches. Remove all patches that you have and apply these. The first one is straight forward. The second one will hopefully fix the livelock issue you have been encountering. People reviewing the patches should note that the second one is slightly different than the one I posted earlier. It removes the BUG_ON in the if condition where we jump to update_holders. The

Using fsdlm/ocfs2_controld.cman, I've rerun the test I've been having problems with on 2.6.30-rc1. After running for several minutes in the same directory on three nodes, the test hangs, and I collect the following information: bull-01 ------- 3053 S< [ocfs2dc] ocfs2_downconvert_thread 3054 S< [dlm_astd] dlm_astd 3055 S< [dlm_scand]

The following series of patches comprises the bulk of our outstanding changes for Ocfs2. Aside from the usual set of cleanups and fixes that were inappropriate for 2.6.25, there are a few highlights: The '/sys/o2cb' directory has been moved to '/sys/fs/o2cb'. The new location meshes better with modern sysfs layout. A symbolic link has been placed in the old location so as to

Hi, I am trying to find an efficient way of applying a linear regression model to different factor combinations in a data frame. I want to obtain the output with minimal or no use of loops if possible. Please let me know if this query is unclear. Thanks, Murtaza

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

Stable folks, When a user creates a local (non-clustered) ocfs2 filesystem, accessing the /sys/kernel/debug/<uuid>/fs_state file will crash the system. This patch fixes the crash by correctly handling local filesystems. The problem was introduced with 2.6.30 and does not affect 2.6.29. It is mainline commit c3d38840abaa45c1c5a5fabbb8ffc9a0d1a764d1.

The R script I run daily for hours looks like this: while (!finish) { Sys.sleep(0.1) time = as.integer(format(Sys.time(), "%H%M")) # always crash here if (new.data.timestamp() <= time) next # ... do some jobs for about 2 minutes ... gc() } Basically it waits for new data, which comes in every 10 minutes, and do some jobs, then gc(), then loop again. It

Greetings, I am reasonably experienced with R but I recently tried to do some clustering using the "cluster" package, in order to see if it would help. I only tried this once with the 1.3.1 version and it worked (I don't quite remember which method I used). Now, I tried with the 1.4.0 version and no clustering function seems to work with matrices that contain NAs, even though

Hello all! I'm working on a library with bignum support, and I wanted to try LLVM as an apparently simpler and more portable system to my current design (a Haskell script which spits out mixed C and assembly). Porting the script to use the LLVM bindings instead of the current hack was pretty easy. But I have a few remaining questions: (1) Are bignums exposed to any higher-level

Hi ! First of all I have to advise you that I don't speak english as well as I whish. So, be lenient. I installed Ubuntu 9.04 on my laptop one month ago. I didn't make any changes, I used it with default settings. I managed to install Football Manager Live (FML) and it worked perfectly ! I installed wine (by apt-get - didn't make any changes either) and then ran the setup.exe from

A reply from stackoverflow suggests I might have hit this bug: https://sourceware.org/bugzilla/show_bug.cgi?id=14023 I can confirm that this glibc bug affects my system (latest CentOS 7). However, as far as I know, R is not multithreaded in its core. Is it possible that some library triggered this? Regards, Steve Tomas Kalibera <tomas.kalibera at gmail.com> ?2019?8?2??? ??4:59??? >

Hi there ! I came across the NetBeans IDE and also the screencasts. Here are the links for screencasts: http://blogs.sun.com/roumen/entry/two_demos_jruby_on_rails D/L Link : http://nbi.netbeans.org/m11/download.html I''m now on Kdevelop and not yet tried NetBeans and its ~80 Mb of D/L. If any of you had tried it out, do post your views. -- Arjun.

I just noticed that the assigns() method has been dropped from action_controller/test_process.rb (http://dev.rubyonrails.org/changeset/3724). Was this an oversight or is there a new process for working with controller instance variables? -- * J * ~
