4.4BSD snapshot (revision 8.1); add 1993 to copyright

Use balloc to extend Ifile.

Initialize on-disk inode structure correctly. Use di_inumber.

Check for out of space condition before extending ifile.

getblk cannot return a NULL bp, don't bother checking for it.

Change LFS_UBWRITE calls to VOP_BWRITE, add inode accounting.

delete VERBOSE #ifdef's

no longer need printfs; extending ifile now works

Do block accounting in terms of disk sectors, not file system blocks.
When initializing an inode, set blocks to 0 (ffs doesn't do this because it has
read the inode from disk where it was zeroed).

compute number of inode blocks in terms of disk blocks

describe ap structure (Kirk); make VDIROP set right

directory ops, unmount, minor cleanup; from Margo Seltzer

vnodeop argument macro expansion

lfs_vfree now returns an int

vnode interface conversion

lint
