Update of /cvsroot/linuxcompressed/linux/mm
In directory usw-pr-cvs1:/tmp/cvs-serv25032/mm
Modified Files:
page_alloc.c
Log Message:
Bug fixes:
o Fixed bug in shrink_comp_cache() which would release a NULL page
o "Fixed" potential bug when unable to allocate page for ptes (vswap)
by pre-allocating one page when initializing compressed cache
o Fixed bug which would cause an oops when fixing memory
watermarks. All zone_balance_* arrays were defined as __initdata, so
they could be accessed by our function after being deallocated. The
fix simply removes the __initdata option from their declaration when
compressed cache is enabled.
Other:
o cleanups in adaptivity.c
