[PATCH 60/68] mxser: remove unnesesary NULL check
From: Kulikov Vasiliy <segooon(a)gmail.com> mxser_transmit_chars(tty, port) is called only from mxser_interrupt(). NULL check is performed in mxser_interrupt() so it is redundant here.

[PATCH 15/68] riscom8: kill use of lock_kernel
From: Alan Cox <alan(a)linux.intel.com> The riscom8 board uses lock_kernel to protect bits of the port setting ioctl logic. We can use the port mutex for this as the logic is internal and will also lock set versus open (a locking property that has been lost somewhere along the way) Signed-off-by: Alan Cox <alan@... 10 Aug 2010 19:07

[PATCH 30/68] serial: Change the wait for carrier locking
From: Alan Cox <alan(a)linux.intel.com> We want to push the lock/unlock into the helper functions so that we can prepare to move to using the tty_port helper. The expansion initially comes out a bit ugly but its worth the temporary expansion IMHO just so we can produce a nice testable series of changes. Signed-o... 10 Aug 2010 19:07

[PATCH 43/68] tty: implement BTM as mutex instead of BKL
From: Arnd Bergmann <arnd(a)arndb.de> The tty locking now follows the rules for mutexes, so we can replace the BKL usage with a new subsystem wide mutex. Using a regular mutex here will change the behaviour when blocked on the BTM from spinning to sleeping, but that should not be visible to the user. Using t... 10 Aug 2010 19:07

[PATCH 36/68] tty: never hold BTM while getting tty_mutex
From: Arnd Bergmann <arnd(a)arndb.de> tty_mutex is never taken with the BTM held, except for two corner cases that are worked around here. We give up the BTM before calling tty_release() in the error path of tty_open(). Similarly, we reorder the locking in ptmx_open() to get tty_mutex before the BTM. Signed-of... 10 Aug 2010 19:07
