[PATCH 1/2] Consolidate Linux access implementation

Thu Nov 10 17:04:00 GMT 2016
This patch consolidates the Linux access implementation on
sysdeps/unix/sysv/linux/access.c. Similar to auto-generation through
syscalls.list, __NR_access is check and __NR_faccessat is used only
for newer architectures (where __NR_access is not defined).
Checked on x86_64.
* sysdeps/unix/sysv/linux/access.c: New file.
* sysdeps/unix/sysv/linux/generic/access.c: Remove file.
