Subject: Make needlessly static data local
X-Git-Tag: v4.7~319
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=deec74eb5296a220caabeb5f12abacd9770d10a2;p=strace

Make needlessly static data local

* syscall.c (get_scno): For POWERPC64 and X86-64, variable currpers
is declared static. But its old data is never used. Convert it
to ordinary local variable.
