4 Subject: [PATCH 1/2] ARM: 6329/1: wire up sys_accept4() on ARM
6 sys_accept4() was added in kernel 2.6.28, but ARM was not updated
7 to include it. The number and types of parameters is such that
8 no ARM-specific processing is needed, so wiring up sys_accept4()
9 just requires defining __NR_accept4 and adding a direct call in
10 the syscall entry table.
12 Tested with an EABI 2.6.35 kernel and Ulrich Drepper's original
13 accept4() test program, modified to define __NR_accept4 for ARM.
15 Using the updated unistd.h also eliminates a warning then building
16 glibc (2.10.2 and newer) about accept4() being unimplemented.
18 Upstream-Status: Backport [2.6.36]
