[PATCH 2/2] xfstests: Add JFS support to _scratch_mkfs_sized

[Michael L. Semon]

This code works, with a little bit of tinkering.  I wanted to shovel 
it off to another function but didn't know what to do with the 
arguments.  In particular, the number_of_blocks value has to come 
after the dev name.

Thanks!

Michael

Subject: [PATCH 2/2] xfstests: Add JFS support to _scratch_mkfs_sized

Add _scratch_mkfs_sized support for JFS.  Calculations are here
due to a jfs_mkfs log calculation issue when the file system size
is smaller than the partition size.  This issue is avoided by
specifying the log size (in megabytes) on the command line.
