cifs: fix return value for cifs_listxattr [ Upstream commit 0c5d6cb6643f48ad3775322f3ebab6c7eb67484e ] If the application buffer was too small to fit all the names we would still count the number of bytes and return this for listxattr. This would then trigger a BUG in usercopy.c Fix the computation of the size so that we return -ERANGE correctly when the buffer is too small. This fixes the kernel BUG for xfstest generic/377 Signed-off-by: Ronnie Sahlberg <lsahlber@redhat.com> Signed-off-by: Steve French <stfrench@microsoft.com> Reviewed-by: Aurelien Aptel <aaptel@suse.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
