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

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

Module Name:    src
Committed By:   ad
Date:           Mon Oct  8 20:19:29 UTC 2007

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

Log Message:
- Don't leave nodes dangling in order to keep track of the inode generation
  number. Free them back to the pool as soon as the referenced file becomes
  unused. Using arc4random() for the generation and ino_t based off the
  node's in-core address is just about as as good as a disk-based file
  system is going to give.
- Add assertion to catch empty directories with linkcount > 1 being freed.
  This fires frequently but I haven't tracked the bug down yet..
- Use kmem_alloc.
