Subject: [PATCH 0/5] tracing: probes: Use heap instead of stack for temporary buffers
Date: Fri, 18 Jul 2025 20:33:58 +0900 [thread overview]
Message-ID: <175283843771.343578.8524137568048302760.stgit@devnote2> (raw)
Hi,
Here is a series of cleanup patches which allocate temporary buffers
and objects on heap (slab) instead of the stack. This reduces a
possibility of stack overflow. This may reduce the performance but
the modified path is not a hot path.
