Pull gfs2 updates from Bob Peterson:
 "We've got nine more patches for this merge window.

   - remove sd_jheightsize to greatly simplify some code (Andreas
     Gruenbacher)

   - fix some comments (Andreas)

   - fix a glock recursion bug when allocation errors occur (Andreas)

   - improve the hole_size function so it returns the entire hole rather
     than figuring it out piecemeal (Andreas)

   - clean up gfs2_stuffed_write_end to remove a lot of redundancy
     (Andreas)

   - clarify code with regard to the way ordered writes are processed
     (Andreas)

   - a bunch of improvements and cleanups of the iomap code to pave the
     way for iomap writes, which is a future patch set (Andreas)

   - fix a bug where block reservations can run off the end of a bitmap
     (Bob Peterson)

   - add Andreas to the MAINTAINERS file (Bob Peterson)"
