This series adds it. Patch 1 stops recvmsg() from holding the socket lock while it waits for data. Patch 2 stops sendmsg() from turning every allocation failure into -ENOMEM, so errors such as -ENETRESET and -EPIPE reach userspace. Patch 3 adds qrtr_shutdown(). Patches 1 and 2 address long-standing behaviour rather than regressions, so they carry no Fixes: tags. Signed-off-by: Chunkai Deng --- To: Manivannan Sadhasivam To: "David S.
