The following file(s) were checked into:
  bonnie.engr.sgi.com:/isms/slinx/2.4.x-xfs


Modid:  2.4.x-xfs:slinx:119372a
linux/fs/xfs/linux/xfs_lrw.c - 1.135
	- remove [ab;-)]use of several xs_attr stats variables here - these
	  crept in during the blocksize code merge, unintentionally.

linux/fs/xfs/pagebuf/page_buf_io.c - 1.34
	- add in several missing uses of STATIC; fix up a few comment typos
	  or now out-of-date comments; make 1st 4/5 function's declarations
	  consistent with the rest of the file.
