Hi everyone, I''ve pushed out my current kernel git tree to a new branch called integration-test. This is meant for integration testing only and should not be run by anyone who doesn''t love crashes. I''ve pulled together a lot of important work from a lot of different people. It includes: The new inode number allocator Delayed inode and directory item updates Scrub,

Sigh. In the previously sent v2 patch the mail 1/4 exceeded the archaic 100,000 chars limit of vger.kernel.org (no complains from checkpatch.pl though). Therefore I now prepared a git-daemon for pulling. Please pull from git://btrfs.giantdisaster.de/git/btrfs integrity-check-patch-v2 Changes v1-v2: - Merge with updated disk flush code - Use bdevname to print the bdev''s name instead of

Hi all, are there any plans that future versions of mkfs.btrfs will do an initial pre-discard for SSDs? (AFAIK mkfs.btrfs does not do this currently) For Ext4, mke2fs does this with the -E discard option. From the mke2fs manpage: -E discard Attempt to discard blocks at mkfs time (discarding blocks initially is useful on solid state devices and sparse / thin-provisioned storage). When

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. --

Hi everyone, The master branch of the btrfs unstable tree: git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable.git master Has a collection of btrfs bug fixes. The three most important fixes here address crashes in the btrfs O_DIRECT code, add a migrate_page operation to avoid metadata corruption as btree pages go through migration, and fix up our NFS support. Otherwise we have

Hi, I try to format a USB memory with a Btrfs. I can format it with mkfs.btrfs without problems. But; when I try to mount it, it fails to mount with the below error messages. But the USB memory works fine with other filesystems (ext4, XFS etc.). So, the hardware is not faulty. tarkane@tarkane:~$ sudo mkfs.btrfs -d single -n 4096 /dev/sdb1 WARNING! - Btrfs v0.18-26-g0030f1d IS EXPERIMENTAL

V2 -> V3: set ''err'' to -ENOMEM when kmalloc() fails. Thanks to Tao. V1 -> V2: Move kmalloc() before mutex_lock(), suggested by Arjan. file_remove_suid() should be called with i_mutex held, file_update_time() too. So move them after mutex_lock(). Plus, check the return value of kmalloc(). Signed-off-by: WANG Cong <amwang@redhat.com> Cc: Arjan

Hello everyone, As Linus discovered, the new btrfs disk format in 2.6.31-git can be problematic if your FS gets forward rolled to the new format and you end up bisecting back to the old code. It would also be nice to have a way to run btrfsck on a root filesystem and do other assorted tasks. So, I''m making live boot usb images for both x86 and x86-64. They should have enough to get
