Modified files:
sys/vm vm_pageout.c
Log:
Be less conservative with a recently added KASSERT. Certain edge
cases with file fragments and read-write mmap's can lead to a situation
where a VM page has odd dirty bits, e.g. 0xFC - due to being dirtied by
an mmap and only the fragment (representing a non-page-aligned end of
file) synced via a filesystem buffer. A correct solution that
guarentees consistent m->dirty for the file EOF case is being
worked on. In the mean time we can't be so conservative in the
KASSERT.
