[PATCH] Cleanup sync_file_range implementation
- From: Adhemerval Zanella <adhemerval dot zanella at linaro dot org>
- To: libc-alpha at sourceware dot org
- Date: Wed, 21 Oct 2015 16:12:35 -0200
- Subject: [PATCH] Cleanup sync_file_range implementation
- Authentication-results: sourceware.org; auth=none
Since GLIBC requires a minimum 2.6.32 kernel, the patch cleanups
the mips code to assume __NR_sync_file_range and the powerpc one
to either assume __NR_sync_file_range2 or __NR_sync_file_range.
Checked on powerpc64le and build for mips (ABIO32, ABIN32, and ABI64).
* sysdeps/unix/sysv/linux/powerpc/powerpc64/sync_file_range.c
(__NR_sync_file_range2): Assume it is always defined.
* sysdeps/unix/sysv/linux/mips/mips32/sync_file_range.c
(__NR_sync_file_range): Assume it is always defined.
