New Revision: 1020

Added:
   branches/endian-safe/libocfs2/include/jbd.h
   branches/endian-safe/libocfs2/slot_map.c
Removed:
   branches/endian-safe/debugfs.ocfs2/include/jbd.h
   branches/endian-safe/libocfs2/include/jfs_compat.h
   branches/endian-safe/libocfs2/include/jfs_user.h
   branches/endian-safe/libocfs2/include/kernel-jbd.h
Modified:
   branches/endian-safe/fsck.ocfs2/journal.c
   branches/endian-safe/libocfs2/Makefile
   branches/endian-safe/libocfs2/chain.c
   branches/endian-safe/libocfs2/dirblock.c
   branches/endian-safe/libocfs2/include/ocfs2.h
   branches/endian-safe/libocfs2/inode.c
   branches/endian-safe/libocfs2/mkjournal.c
   branches/endian-safe/mkfs.ocfs2/mkfs.c
   branches/endian-safe/mkfs.ocfs2/mkfs.h
   branches/endian-safe/tunefs.ocfs2/tunefs.c
Log:
swap with libocfs2 in mkfs

o swap structures before they're written, swap back if not freed
o get rid of noisy jbd header mess, just use debugfs' jbd.h for structs
o hoist duplicate dirent walking and swapping code into helper func
o teach libocfs2 to swap the slot map
