Subject: Change printargs to return RVAL_DECODED
X-Git-Tag: v4.15~81
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=37c4d4bcfcfe169e5adc2935168ef30aa565d771;p=strace

Change printargs to return RVAL_DECODED

As printargs is invoked as a generic syscall decoder only and
it is not supposed to print anything on exiting, change printargs
to return RVAL_DECODED so it would not be called on exiting at all.

* util.c (printargs): Print args unconditionally, return RVAL_DECODED.
