Subject: SUNRPC: Handle ENOMEM in call_transmit_status()
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=132cbe2f182ab535e0a7fa309d2c73ed6257a246;p=linux-block.git

SUNRPC: Handle ENOMEM in call_transmit_status()

[ Upstream commit d3c15033b240767d0287f1c4a529cbbe2d5ded8a ]

Both call_transmit() and call_bc_transmit() can now return ENOMEM, so
let's make sure that we handle the errors gracefully.
