Hi,
I understand that we are not supposed to extend subfsals and should move to
Stackable FSALs. But, since it is not possible in some cases (e.g.
open_by_handle is not supported by the kernel), subfsal has to stay.
Currently, the referrals decision is made by FSAL_VFS depending on a specific
set of attributes and user.fs_location xattr value. If a subfsal wants to
achieve this with some other mechanism, there is no way to do that in the
current code. So, I wanted to extend the referrals functionality in FSAL_VFS
and make it more flexible by allowing subfsal to change the behavior or not
support referrals at all.
Any thoughts?
Thanks,
Sriram
