Message

Two extensions to /proc/PID/comm implementation to ease extending
TASK_COMM length: first is a fix for silent truncation when changing
thread name, second allows atomic query of kernel's TASK_COMM size.

Michał Mirosław (2):
  procfs: signal /proc/PID/comm write truncation
  procfs: lseek(/proc/PID/comm, 0, SEEK_END)
