Modified files:
sys/ufs/ffs ffs_balloc.c ffs_vfsops.c
sys/ufs/ufs inode.h ufs_inode.c
Log:
Eliminate the i_devvp field from the incore UFS inodes, we can
get the same value from ip->i_ump->um_devvp.
This saves a pointer in the memory copies of inodes, which can
easily run into several hundred kilobytes.
The extra indirection is unmeasurable in benchmarks.
