[Cluster-devel] GFS2: Pre-pull patch posting (merge window)

[Steven Whitehouse]

Hi,

Not a huge number of patches this time. Some notable new features
though:
 - Glock stats gathering (v. useful for performance analysis)
 - FITRIM ioctl support
 - Sorting the ordered write list (big performance increase when the workload
   doesn't result in the write requests being nicely ordered to start with)

Plus a few clean ups, and bug fixes in addition,

Steve.
