and a final revert i forgot 

2002/07/11 23:44:13-00:00 !flatcap
new function headers and a few function moves

2002/07/11 16:20:32-00:00 !flatcap
whitespace and include guards

2002/07/11 13:18:11-00:00 !flatcap
start to break up the dependency loops in the header files

2002/07/02 23:47:10-00:00 !antona
Global replacement of __[su]{8,16,32,64} with [su]{8,16,32,64} and layout.h define it.

2002/06/06 20:47:31-00:00 !antona
The beginning of the directory operations! Introduce dir.[hc] and ntfs_lookup_inode_by_name().

2002/06/01 00:41:45-00:00 !antona
huge update!

2002/04/20 23:09:42-00:00 !antona
Port attribute lookup functions with attribute list support from ntfs tng driver. Port/reimplement extent mft record handling code as well. Rename out all dollar signs from type names and constants. Adapt all callers to new API. Note mkntfs is currently broken due to some needed work.

2002/04/19 21:21:46-00:00 !antona
Remove compile time warning...

2002/04/19 21:09:55-00:00 !antona
Finished provisional inode.c::ntfs_{open,close}_inode() functions. Also, started defining API provided by attrib.[ch], so far only done search context related stuff.

2002/04/19 18:27:45-00:00 !antona
Bah. Typo fix.

2002/04/19 18:23:56-00:00 !antona
Add foundation of new inode API.

2002/04/15 22:35:07-00:00 !antona
Preliminary ntfs_inode structure. We shall see if that is all we need. (-;
