[PATCH 0/6] More n_tty fixes

Show all headers | View raw

Hi Greg,

This series collects up several fixes for N_TTY.

The first patch fixes read() when VMIN > 0 & VTIME = 0 (so called "record mode").
By ripping out a marginal optimization, the overall code is greatly simplified
and "record mode" read()s won't hang :)

Patch 2 removes the pointless fasync() notification to line disciplines.
Patches 3,4 & 5 fix hangup races with enabling/disabling signal-driven i/o.
Patch 6 is a minor cleanup for a condition test that can never be true.

Regards,

Peter Hurley (6):
  n_tty: Always wake up read()/poll() if new input
  tty, n_tty: Remove fasync() ldisc notification
  tty: Add fasync() hung up file operation
  tty: Fix ioctl(FIOASYNC) on hungup file
  n_tty: Fix stuck write wakeup
  n_tty: Remove tty count checks from unthrottle
