Log Message:
ffs: apply the remaining ffs_snapshot.c part of this FreeBSD commit:
commit 364ed814e7285c8216d8a201d3ab3674eb34ce29
Author: Kirk McKusick <[email protected]>
Date: Thu Dec 9 21:24:00 2004 +0000
Fixes a bug that caused UFS2 filesystems bigger than 2TB to
prematurely report that they were full and/or to panic the kernel
with the message ``ffs_clusteralloc: allocated out of group''.
Submitted by: Henry Whincup <[email protected]>
MFC after: 1 week
all the other changes in that commit were applied previously by others:
- sborrill commmitted ffs_alloc.c rev 1.123 in 2009
- simonb committed ffs_alloc.c rev 1.110 in 2008
- the ffs_clusteralloc() part is not needed because we no longer have
that function.
