CVS commit: [vmlocking] src/sys/fs/tmpfs

[Andrew Doran <ad%netbsd.org@localhost>]

Module Name:    src
Committed By:   ad
Date:           Tue Sep 18 16:05:29 UTC 2007

Modified Files:
        src/sys/fs/tmpfs [vmlocking]: tmpfs_pool.c

Log Message:
tmpfs_pool_page_alloc:

- If we can't allocate a page, just return NULL instead of panicing.

- Specify PR_NOWAIT to the back-end allocator. This is a bit risky since
  we are relying on the results of a stale check that there is free memory,
  but for now it's better than failing allocations because another thread
  has kernel_map locked.
