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

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

Module Name:    src
Committed By:   ad
Date:           Tue Aug 21 20:01:31 UTC 2007

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

Log Message:
- Add locking around tmpfs shared data structures and mark it MP safe.
  It's enough to last for about 45m of fsx+postmark, but it doesn't
  survive SGI fsstress yet.
- Close a race where multiple vnodes could maybe have been allocated
  for a tmpnode with linkcount > 1.
