Hi,

This patch set adds real support of extended attributes on
HFS+ file system.

Thanks for looking into this. I'll give it a try as soon as possible.

HFS+ keeps extended attributes as key-value pairs in special
metadata file - Attributes tree. Moreover, userInfo and
finderInfo fields in Catalog File and Catalog Folder records
are accessible to an user as com.apple.FinderInfo extended
attribute.

For support of extended attributes on HFS+:
1. It was added necessary on-disk layout declarations
related to Attributes tree into hfsplus_raw.h file.
2. It was added attributes.c file with implementation of
functionality of manipulation by records in Attributes
tree.
3. It was reworked hfsplus_listxattr, hfsplus_getxattr,
hfsplus_setxattr functions in ioctl.c. Moreover, it was
added hfsplus_removexattr method.

With the best regards,
Vyacheslav Dubeyko.
