hi folks,
We've removed the cursor operations, and gone back to Andreas'
original, simpler list approach. Revised versions of the two
extattr man pages are in the XFS CVS repository, or use:
http://acl.bestbits.at/man/extattr.2.html
http://acl.bestbits.at/man/extattr.5.html
I notice that 2.4.15-pre3 doesn't have the patch below - Linus,
Alan, could you please apply it? - it will help us a great deal.
This would be useful to the ext2/ext3, InterMezzo/SnapFS, NTFS,
XFS, JFS and BeFS filesystem implementations for Linux, and to
any other filesystems planning to support extended attributes
in the future as well.
many thanks.
