similar to: [PATCH] Btrfs: fix uncheck memory allocations

To make Btrfs code more robust, several return value checks where memory allocation can fail are introduced. I use BUG_ON where I don''t know how to handle the error properly, which increases the number of using the notorious BUG_ON, though.

Hi, I''ve discovered that some btrfs code doesn''t check whether kmalloc() call succeeded. I poorly understand what this code does and how it can be changed, maybe it would be happy with __GFP_NOFAIL. Also there are BUG_ON() after kmalloc()''s, if they could be changed not to panic it would be great. --- ./fs/btrfs/compression.c 2010-07-06 16:45:48.000000000 +0400 +++

Hi all - The following 9 patches add more error handling to the btrfs code: - Add btrfs_panic - Catch locking failures in {set,clear}_extent_bit - Push up set_extent_bit errors to callers - Push up lock_extent errors to callers - Push up clear_extent_bit errors to callers - Push up unlock_extent errors to callers - Make pin_down_extent return void - Push up btrfs_pin_extent errors to

I removed this in an earlier commit and I was wrong. Because compression can return from filemap_fdatawrite() without having actually set any of it''s pages as writeback() it can make filemap_fdatawait() do essentially nothing, and then we won''t find any ordered extents because they may not have been created yet. So not only does this make fsync() completely useless, but it will

These xm info, top, dmesg and log requre no parameter. But log''s error message differs from other 3 command''s error messages, when parameter is given. # xm log 1 Error: ''xm log'' requires 0 argument. log Print the xend log Other 3 commands ignore parameter. I think it might be better symmetricalize. Signed-off-by: Yoshinori

Hi all, I have learned about LLVM backend passes. LLVM IR changes its format four times until final output assembly/object through SelectionDAG, MachineInstr, MCInst. MCInst format layer seems to be called as "MC layer" officially. What about MachineInstr format layer? It seems to be called as "MI layer", is it officially? Please tell me there is good name for representing

Hi, this is my first post and contribution to Btrfs. I wrote a documentation on how to debug Btrfs with GDB on UML(User Mode Linux). https://btrfs.wiki.kernel.org/index.php/Debugging_Btrfs_with_GDB This document might be little bit boring for Btrfs hackers, but for beginners who want to join Btrfs development, it is worth reading, I think. (BTW, I''m a beginner, too :D) Thank you. --

In btrfs if we mount with "compress" we have no way to disable compressing by remounting (mount -o remount /mnt/btrfs), only by unmounting and mounting without "compress". This patch adds "nocompress" mount option which can be used to remount the filesystem without compression: # mount -o remount,nocompress /mnt/btrfs This option is usefull in cases when we have a

Document those places in the btrfs code which are BUGing on non-fatal error conditions that should be handled by proper error paths. This makes it easier to distinguish between what needs fixing versus which BUG_ON''s we might want to keep (to trap code bugs, unexpected inconsistencies, etc). Do this with a trivial macro, ''btrfs_fixable_bug_on'' which just defines to

Hi all - Here''s my current error handling patchset, against 3.1-rc8. Almost all of this patchset is preparing for actual error handling. Before we start in on that work, I''m trying to reduce the surface we need to worry about. It turns out that there is a ton of code that returns an error code but never actually reports an error. The patchset has grown to 65 patches. 46 of them

After running ceph on XFS for some time, I decided to try btrfs again. Performance with the current "for-linux-min" branch and big metadata is much better. The only problem (?) I''m still seeing is a warning that seems to occur from time to time: [87703.784552] ------------[ cut here ]------------ [87703.789759] WARNING: at fs/btrfs/inode.c:2103

Buenas tardes para todos, Me gustaría automatizar la descarga de librerias cuando ejecuto una función que estoy por terminar. Supongamos que la función se llama foo y require las librerias A y B. Una manera fácil de cargar las librerias dentro de foo es: foo <- function(argumentos){ require(A) require(B) # hacer transformaciones, cálculos y gráficos aquí

Hello! I have this page where I list all users in a table. There is checkbox in every row. My User-model has a "checked"-attribute. I have implemented the checkboxes like this: <%= check_box("user[]", "checked") %> Which outputs this: <input id="user_12_checked" name="user[12][checked]" type="checkbox" value="1"

Hi all I have a check box in form, and I would like to enable/disable it according to the value of the check box.. <% form_for(:query, @query,.... <%= f.check_box(:all_categories, :disabled => true, :onchange =>''javascript:all_categories();'') -%><%=l :All_categories %> I would like to have something like :disabled => { @query.all_categories.to_i

I am trying to implement a check all and uncheck all button for my check boxes. Here is what I have below. I am getting this error each time: Error: document.myform.add_visit_for_this_Pt has no properties Source File: http://localhost:3000/AddPatientVisit/addvisits Line: 1 Strange that I can''t seem to pass value into the function. Thanks for your help! <SCRIPT

We have been unconditionally allocating a new bio and re-adding all pages from our original bio to the new bio. This is needed if our original bio is larger than our stripe size, but if it is smaller than the stripe size then there is no need to do this. So check the map length and if we are under that then go ahead and submit the original bio. Thanks, Signed-off-by: Josef Bacik
