CVS commit: src/sys/kern

[Manuel Bouyer <bouyer%netbsd.org@localhost>]

Module Name:    src
Committed By:   bouyer
Date:           Tue Mar 15 18:22:24 UTC 2005

Modified Files:
        src/sys/kern: subr_extent.c

Log Message:
Fix off-by-one bug which would cause a region at the end of the extent
to be alloctated multiple times:
- we're allocating region of size 1
- there are holes in the extent, but all of size larger than 1
- there are 2 contigous allocations at the end of the extent, the last one
  being of size 1.
While there fix a DIAGNOSTIC check: to check that a region is inside the extent
we need to check start and end, not only start.
