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 drivers/tty/n_tty.c | 46 ++++------------------------------------------ drivers/tty/tty_io.c | 19 +++++++++---------- include/linux/tty_ldisc.h | 6 ------ 3 files changed, 13 insertions(+), 58 deletions(-) -- 2.6.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
