Log message:
Bugzilla 230803:
Allow GFS to take advantage of VFS's "bd_inode_backing_dev_info" setting
that overrides diaper device's generic readahead value. Various benchmarks
show we can achieve 2x more performance with large sequential write.
Option is controlled by a new GFS tunable (seq_readahead).
