[1/1] fix breakage in SOCKET_URING_OP_SIOC* implementation commit: 1ba0e9d69b2000e95267c888cbfa91d823388d47 Best regards,

In 8e9fad0e70b7 "io_uring: Add io_uring command support for sockets" you've got an include of asm-generic/ioctls.h done in io_uring/uring_cmd.c. That had been done for the sake of this chunk - + ret = prot->ioctl(sk, SIOCINQ, &arg); + if (ret) + return ret; + return arg; + case SOCKET_URING_OP_SIOCOUTQ: + ret = prot->ioctl(sk, SIOCOUTQ, &arg); SIOC{IN,OUT}Q are defined to symbols (FIONREAD and TIOCOUTQ) that come from ioctls.h, all right, but the values vary by the architecture. FIONREAD is 0x467F on mips 0x4004667F on alpha, powerpc and sparc 0x8004667F on sh and xtensa 0x541B everywhere else TIOCOUTQ is 0x7472 on mips 0x40047473 on alpha, powerpc and sparc 0x80047473 on sh and xtensa 0x5411 everywhere else ->ioctl() expects the same values it would've gotten from userland; all places where we compare with SIOC{IN,OUT}Q are using asm/ioctls.h, so they pick the correct values. io_uring_cmd_sock(), OTOH, ends up passing the default ones.
