The patch titled
nfsd: validate filehandle type in fsid_source
has been removed from the -mm tree. Its filename was
nfsd-validate-filehandle-type-in-fsid_source.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: nfsd: validate filehandle type in fsid_source
From: Neil Brown <[EMAIL PROTECTED]>
fsid_source decided where to get the 'fsid' number to return for a GETATTR
based on the type of filehandle. It can be from the device, from the fsid,
or from the UUID.
It is possible for the filehandle to be inconsistent with the export
information, so make sure the export information actually has the info
implied by the value returned by fsid_source.
