If we have particularly full nodes, we could call btrfs_node_blockptr up to 32 times, which is 32 pairs of kmap/kunmap, which _sucks_. So go ahead and map the extent buffer while we look for readahead targets.

hello, Chris In the next several months, I will have a lot of spare time. I will be happy if you assign some work to me. I have learn linux kernel for years but only fix a few small bugs in IP stack. In the past few months, I read some EXT4/VFS codes. I began reading source of btrfs ten days ago and have read it twice now. Regards YZ

Two patches follow this message. One fixes the default implementation of SEEK_HOLE/DATA. This patch applies atop Josef's last posted patch. The second patch implements the same on ocfs2. The test tool for the same is available here. http://oss.oracle.com/~smushran/seek_data/seek_test.c It is improved since the last post. It runs cleanly on zfs, ocfs2 and ext3 (default behavior).

All, Please review the patches backported to 1.4 from mainline. Sunil

The inode eviction can be very slow, because during eviction we tell the VFS to truncate all of the inode''s pages. This results in calls to btrfs_invalidatepage() which in turn does calls to lock_extent_bits() and clear_extent_bit(). These calls result in too many merges and splits of extent_state structures, which consume a lot of time and cpu when the inode has many pages. In some

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

Greeting all, I have a bit of a complicated question. I have two ethernet devices, eth1 and eth2. eth1 is where my internet comes from. It is in the form of 202.172.122.208/29. It has another IP range, 202.172.122.72/29. What I want to be able to do is route 202.172.122.72/29 to eth2, so that other machines can use those IPs, any ideas on how to do this, I cannot work out how to do this.

Hello everybody, I've my Gentoo's /usr/portage on a loopback btrfs. Just wanted to sync and got an oops. I've a rsync and a ls process in status D now. The system has been in suspend (tuxonice 3.0-rc3) with mounted btrfs, perhaps that is related?

Hello, I test right now the beauty of zfs. I have installed opensolaris on a spare server to test nfs exports.

With Mac OS X as client I can mount the filesystem in Finder.app with nfs://server/tank1/nfsshare, but if I copy a file an error ocours. Finder say "The

ocfs2 was hand-calling vfs_follow_link(), but there's no point to that. Let's use page_follow_link_light() and nd_set_link().

Hi Guys, I am wondering about mail deduplication. I am looking into the possibility of seperating out all of the message bodies with multiple parts inside mail that is recived from `dovecot` and hashing them all. The idea is that by hashing all of the parts inside the email, I will be able to ensure that each part of the email will only be saved once. This means that attachments & common

Hello, I''m seeing a lot of warnings in dmesg with a BTRFS filesystem. I''m using the 3.1 kernel, I found a patch for these warnings ( http://marc.info/?l=linux-btrfs&m=131547325515336&w=2) <http://marc.info/?l=linux-btrfs&m=131547325515336&w=2>, but that patch has already been included in 3.1. Are there any other patches I can try? I''m using

I am running r79979 of Asterisk Trunk, and I am having problems trying to use app_queue.so. I want to use the extension 510 to be a line where users can call technical support. Extensions 511 and 512 are used by the operators to dynamically make themselves a Queue Member or not. So, operators call 511, and they should get added to the Queue as a Queue member. When users call 510 then, it

Hi everyone, I described the reflink operation at the Linux Storage & Filesystems Workshop last month. Originally implemented as an ocfs2-specific ioctl, the consensus was that it should be a syscall from the get-go. Here's some first-cut patches. For people who have not seen reflink, either at LSF or on the ocfs2 wiki, the first patch contains Documentation/filesystems/reflink.txt to
