CVS commit: src/sys/lib/libsa

[David Laight <dsl%netbsd.org@localhost>]

Module Name:    src
Committed By:   dsl
Date:           Fri Aug 22 21:33:53 UTC 2003

Modified Files:
        src/sys/lib/libsa: ufs.c

Log Message:
Reduce memory footprint:
- use file buffer for all block reads
- only save a small amount of the indirect block list
Allows i386 bootxx_ufs code to load /boot from a filesystem with 32k blocks
while still fitting inside 64k of memory.
Code size reduced as well (by ~1k on i386).
It ought to be possible to use a buffer that is smaller than a filesystem
block.  This might be needed in order to boot from filesystems with larger
block sizes.
