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.
