Subject: Assume accept4 on ARM for kernels 2.6.36 and later
Date: Wed, 16 May 2012 10:40:00 -0000 [thread overview]
Message-ID: <Pine.LNX.4.64.1205161038540.11537@digraph.polyomino.org.uk> (raw)
ARM Linux kernels added the accept4 syscall in 2.6.36; I've now applied
this kernel-features.h patch to define __ASSUME_ACCEPT4 accordingly.
