Hello everyone, Btrfs v0.14 is now available for download. Please note the disk format has changed, and it is not compatible with older versions of Btrfs. For downloads and documention, please see the Btrfs project page: http://btrfs.wiki.kernel.org The oss.oracle.com Btrfs project page will soon start redirecting here. v0.14 has a few performance fixes and closes some races that could have

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
