From: Adrian Hunter Date: Thu, 25 Nov 2021 07:14:57 +0000 (+0200) Subject: perf inject: Fix itrace space allowed for new attributes X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c29d9792607e67ed8a3f6e9db0d96836d885a8c5;p=linux.git perf inject: Fix itrace space allowed for new attributes The space allowed for new attributes can be too small if existing header information is large. That can happen, for example, if there are very many CPUs, due to having an event ID per CPU per event being stored in the header information. Fix by adding the existing header.data_offset. Also increase the extra space allowed to 8KiB and align to a 4KiB boundary for neatness.
