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

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

Hi all, I want to open a device(/dev/sda1, /dev/hda2 etc) in which my file exists. I've used 'stat' system call to get the device id. But now I want the device name from this id(st_dev). How to get that one? Or Do you have any other method to know the device name where my file resides? Thanks Bollywood, fun, friendship, sports and more. You name it, we have it on

V1->V2: Check to see if our current ppos is >= i_size after a short DIO read, just in case it was actually a short read and we need to just return. This is similar to what already happens in the write case. If we have a short read while doing O_DIRECT, instead of just returning, fallthrough and try to read the rest via buffered IO. BTRFS needs this because if we encounter a compressed or

Hi, These three patches fix the problems in the version two. And them base on the Tao's patches: ocfs2/xattr: xattr improvement The first patch fix some problem in xattr code. The second patch add security EA support. The third patch add ACL support. Best regards, tiger

Hi, This is the second batch of Ocfs2 patches intended for the merge window. The 1st batch were sent out previously: http://lkml.org/lkml/2008/12/19/280 The bulk of this set is comprised of Jan Kara's patches to add quota support to Ocfs2. Many of the quota patches are to generic code, which I carried to make merging of the Ocfs2 support easier. All of the non-ocfs2 patches should have
