72 why not use it for unix-specific info like file owner or access rights? This
73 driver can do it. If you chown/chgrp/chmod on a hpfs partition, extended
77 they're just changed. It means that when your default uid=0 and you type
79 extended attribute UID=0. And when you umount the fs and mount it again with
84 number. Currently this driver cannot resize extended attributes - it means
94 chgrp symlinks but I don't know what is it good for. chmoding symlink results
97 stored in very crazy way. They tried to do it so that link changes when file is
98 moved ... sometimes it works. But the link is partly stored in directory
110 partition. It marked file name codepage as 850 - good. But when I again booted
111 Czech OS/2, the file was completely inaccessible under any name. It seems that
113 name it's comparing to with its code page (850). These could never match. Is it
123 OK, I could implement complex codepage support to this driver but I think it
125 So this driver simply uses first codepage it finds for uppercasing and
137 and I'll make it. However, this driver should detect presence of HPFS386
144 driver allows you to do it. chkdsk ignores such errors.
148 (one directory, if it's large, has dirents in tree on HPFS) must be replaced
160 You can't rename over directories (what is it good for?).
162 Renaming files so that only case changes doesn't work. This driver supports it
166 reasons. If you extremely wish to update them, let me know, I'll write it (but
167 it will be slow).
169 When the system is out of memory and swap, it may slightly corrupt filesystem
170 (lost files, unbalanced directories). (I guess all filesystem may do it).
173 anybody know what does it mean?
180 unbalanced trees too :-) but both HPFS and HPFS386 contain bug that it rarely
182 correctly and writes warning if it finds them. If you see this message, this is
185 again. Do it in Linux, not OS/2! If you see this message in directory that is
186 whole created by this driver, it is BUG - let me know about it.
194 Sometimes (I think it's random) when you create a file with one-char name under
195 OS/2, OS/2 marks it as 'long'. chkdsk then removes this flag saying "Minor fs
198 File names like "a .b" are marked as 'long' by OS/2 but chkdsk "corrects" it and

238      Changed behaviour on HPFS386: It is now possible to operate on HPFS386 in

250      Fixed a bug that it set badly one flag in large anode tree (it was not
261      Fixed a bug that it didn't allow creation of files > 128M (it should be 2G)
268      Now it tries to truncate the file if there's not enough space when deleting
270 2.00 Fixed a bug in rename (it was there since 1.96)
274      Fixed race-condition in buffer code - it is in all filesystems in Linux;
275         when reading device (cat /dev/hda) while creating files on it, files
281      Now it works with Japanese version of OS/2
288      Reschedule points added so that it doesn't lock CPU long time
289      It should work in read-only mode on Warp Server
290 2.07 More fixes for Warp Server. Now it really works
