From: Chuck Lever <chuck.lever@xxxxxxxxxx>
Build out the patch series to address the longstanding bug pointed
out by J David and Rick Macklem.
At least during NFSv4 COMPOUND encoding, using
write_bytes_to_xdr_buf() seems less brittle than saving a pointer
into the XDR encoding buffer.
I have one more patch to add (not yet included) that addresses the
issue in the NFSv4 READ and READ_PLUS encoders.
Changes since RFC:
- Document the guarantees around pointer returned by xdr_reserve_space()
- Use write_bytes_to_xdr_buf() instead
Chuck Lever (2):
NFSD: Encode COMPOUND operation status on page boundaries
SUNRPC: Document validity guarantees of the pointer returned by
reserve_space
