CVS commit: src/sys/ufs/ffs
Module Name: src
Committed By: hannken
Date: Thu Jul 31 09:35:09 UTC 2008
Resolve a deadlock when fs_nodealloccg() initializes more inodes on
an UFS2 file system. With the current cylinder group buffer busy it
calls ffs_getblk(). This runs through copy-on-write and may need the
current cylinder group buffer to allocate a new block for the snapshot.
While here write the cylinder group buffer synchronously after
cg_initediblk was changed because fsck_ffs will trust it.
