[Steve B. <sb...@us...>]

Release 1.0.17 of JFS was made available today.

Drop 55 on April 2, 2002 (jfs-2.4-1.0.17.tar.gz
and jfsutils-1.0.17.tar.gz) includes fixes to the file
system and utilities.

Utilities changes

- more rigorous dtree validation in fsck.jfs
- fix fsck.jfs to write to the fsck.jfs log properly on big endian machines
- fix xchklog to read the fsck.jfs log properly on big endian machines
- fix xpeek to display/modify PXD information properly on big endian
  machines
- replace fsck.jfs heartbeat with alarm() based heartbeat
  (Christoph Hellwig)
- improve mkfs.jfs and fsck.jfs parameter parsing and usage alerts
- messaging code cleanup, logredo code cleanup, general code cleanup (all)

File System changes

- Call sb_set_blocksize instead of set_blocksize in 2.5 (Christoph Hellwig)
- Replace strtok by strsep (Christoph Hellwig)
- Store entire device number in log superblock rather than just the minor.
- Include file clean (Christoph Hellwig)
- Fix race introduced by thread handling cleanups (Christoph Hellwig)
- Detect dtree corruption to avoid infinite loop
- JFS needs to include completion.h
- Support external log(journal) device file system work part 1
  (Christoph Hellwig)
- Store device number in JFS superblock and log superblock. This adds
  robustness to external journal replaying in case the device number
  changes between reboots.
- Superblock changes needed to support external journal. Removed some
  never-used fields and added a couple new ones.  The external
  journal support is not yet in mkfs.jfs and fsck.jfs, but is coming soon.
