SVN rev 183124 on 2008-09-17 20:30:42Z by jhb
MFC: 173901,173918
- Tidy up: Add comments. Eliminate the pointless
malloc_type_allocated(..., 0) calls that occur when contigmalloc() has
failed. Eliminate the acquisition and release of the page queues lock
from vm_page_release_contig(). Rename contigmalloc2() to
contigmapping(), reflecting what it does.
- Make contigmalloc(9)'s page laundering more robust. Specifically, use
vm_pageout_fallback_object_lock() in vm_contig_launder_page() to better
handle a lock-ordering problem. Consequently, trylock's failure on the
page's containing object no longer implies that the page cannot be
laundered.
