Subject: mpers.awk: relax union member name absence check
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=27a1a3f3eb644066cdae4f7004c56953da1ca83d;p=strace

mpers.awk: relax union member name absence check

This fixes mpersing of unions containing nameless members,
e.g. struct btrfs_ioctl_vol_args_v2.

* mpers.awk (what_is): Print names of union_type members as is.
