Hello,
I have an XFS filesystem containing files and symlinks with application-specific EAs in the user namespace. The files, symlinks and their EAs were created while running a 2.4 kernel.
In 2.6 kernels access to user EAs was prevented for symlinks. My problem is that i have to upgrade the kernel from 2.4 to 2.6 series and i have to have access to all the EAs after upgrade. Is there a way to read user EAs off of symlinks on an XFS filesystem on a 2.6 kernel either from userspace or from a filter driver sitting between VFS and XFS filesystem code?
I would appreciate it very much if somebody could point me towards a solution.

If you want to do it at user code level, you could note the symlink,
follow it to the "real" name, and read the EA there. I don't see any
easy way to force the kernel to follow the symlink.
