[PATCH] nfsd: check for read-only exports before setting acls
We must check for MAY_SATTR before setting acls, which includes checking for read-only exports: the lower-level setxattr operation that eventually sets the acl cannot check export-level restrictions. Bug reported by Martin Walter <mawa@uni-freiburg.de>.
