SVN rev 205349 on 2010-03-19 22:39:27Z by attilio
MFC 181019, 183474, 191277, and 191626:
- Move the code for doing out-of-memory grass from vm_pageout_scan()
into the separate function vm_pageout_oom(). Supply a parameter for
vm_pageout_oom() describing a reason for the call.
- Call vm_pageout_oom() from the swp_pager_meta_build() when swap zone
is exhausted.
- In both pageout oom handler and vm_daemon, acquire the reference to
the vmspace of the examined process instead of directly accessing its
vmspace, that may change. Also, as an optimization, check for P_INEXEC
flag before examining the process.
