Subject: missing: always use __NR_ as prefix for syscall numbers
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=8053a2643f85274e7f4a3ca2bf1f450756a288f2;p=elogind.git

missing: always use __NR_ as prefix for syscall numbers

Apparently, both __NR_ and SYS_ are useful, but we mostly use __NR_
hence use it for these two cases too, so that we settle on __NR_
exclusively.
