>Description:
ufsspec_close() and ufsfifo_close() use ITIMES(), which will invalidate
the count in fs->lfs_uinodes if the inode was not already modified,
leading to subsequent panic.
>How-To-Repeat:
Access a spec dev node on an LFS filesystem while doing heavy concurrent
IO.
>Fix:
Suggest lfsspec_close() and lfsfifo_close() that use LFS_ITIMES()
