In reply to: Jiri Slaby: "[PATCH 02/68] TTY: tty_io, remove buffer re-assignments"
Next in thread: Jiri Slaby: "[PATCH 04/68] TTY: remove minor_num from tty_driver"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

This changes flags' type to ulong which is appropriate for all the
set/clear_bits performed in the drivers..
