Subject: NFSv4: nfs4_decode_dirent must clear entry->fattr->valid
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=4f082222fad3c8471abe0c8e8f18c72f335a34c7;p=deliverable%2Flinux.git

NFSv4: nfs4_decode_dirent must clear entry->fattr->valid

Otherwise, we may end up reading uninitialised data from the resulting
struct nfs_fattr.
