Subject: [PATCH next] netfilter: nf_conntrack_h323: Correct indentation when H323_TRACE defined
Date: Thu, 26 Mar 2026 20:18:19 +0000 [thread overview]
Message-ID: <20260326201819.3900-1-david.laight.linux@gmail.com> (raw)
From: David Laight <david.laight.linux@gmail.com>
The trace lines are indented using PRINT("%*.s", xx, " ").
Userspace will treat this as "%*.0s" and will output no characters
when 'xx' is zero, the kernel treats it as "%*s" and will output
a single ' ' - which is probably what is intended.
Change all the formats to "%*s" removing the default precision.
This gives a single space indent when level is zero.
