Revision 4ce159890c00e2cc705e955a939bf1dca7b07ab8 authored by Dave Chinner on 27 January 2011, 01:17:58 UTC, committed by Alex Elder on 28 January 2011, 15:05:36 UTC 
xfs: prevent extsize alignment from exceeding maximum extent size
 
When doing delayed allocation, if the allocation size is for a
maximally sized extent, extent size alignment can push it over this
limit. This results in an assert failure in xfs_bmbt_set_allf() as
the extent length is too large to find in the extent record.

Fix this by ensuring that we allow for space that extent size
alignment requires (up to 2 * (extsize -1) blocks as we have to
handle both head and tail alignment) when limiting the maximum size
of the extent.
