Re: [PATCH v5 3/3] treewide: Switch from tsk->comm to tsk->comm_str which is 64 bytes long

From: Askar Safin <hidden>

Also in: bpf, linux-fsdevel, linux-mm, linux-perf-users, lkml

where TASK_COMM_EXT_LEN is 64-bytes.

Why 64? As well as I understand, comm is initialized from executable file name by default. And it is usually limited by 256 (or 255?) bytes. So, please, make limit 256 bytes.
