Subject: XFS status update for May 2012
Date: Mon, 18 Jun 2012 08:08:53 -0400 [thread overview]
Message-ID: <20120618120853.GA15480@infradead.org> (raw)
May saw the release of Linux 3.4, including a decent sized XFS update.
Remarkable XFS features in Linux 3.4 include moving over all metadata
updates to use transactions, the addition of a work queue for the
low-level allocator code to avoid stack overflows due to extreme stack
use in the Linux VM/VFS call chain, better xattr operation tracing,
fixes for a long-standing but hard to hit deadlock when using the XFS
real time subvolume, and big improvements in disk quota scalability.
The final diffstat for XFS in Linux 3.4 is:
61 files changed, 1692 insertions(+), 2356 deletions(-)
In the meantime the merge window for Linux 3.5 opened, and another large
update has been merged into Linus' tree. Interesting changes in Linux
3.5-rc1 include improved error handling on buffer write failures,
a drastic reduction of locking overhead when doing high-IOPS direct I/O,
removal of the old xfsbufd daemon in favor of writing most run-time
metadata from the xfsaild daemon, deferral of CIL pushes to decouple
user space metadata I/O from log writeback, and last but not least the
addition of the SEEK_DATA/SEEK_HOLE lseek arguments that allow user space
programs to deal with sparse files efficiently. Traffic on the mailing list
has been a bit quiet in May, mostly focusing on a wide range of bug fixes,
but little new features.
On the user space side xfs_repair saw a few bug fixes posted to the list
that didn't make it to the repository yet, while xfstests saw it's usual
amount of minor bug fixes.
