Hi!
[ Upstream commit a948b1142cae66785521a389cab2cce74069b547 ]
Since commit 9a6944fee68e ("tracing: Add a verifier to check string pointers for trace events"), which was merged in v5.13-rc1, TP_printk() no longer tacitly supports the "%.*s" format specifier.
These are low value tracepoints, so just remove them.
So I understand we want this for mainline, but AFAICT 5.10 does not have 9a6944fee68e ("tracing: Add a verifier to check string pointers for trace events") commit, so this does not fix any bug and removal of tracepoints can be surprising.
Best regards, Pavel
