2007-02-11[PATCH] Char: mxser_new, fix twice resource releasingJiri Slaby
Because brd->info is not NULLed, resources are released twice. NULL it in pci_remove function. Also take care of retval and releasing in pci_probe -- mxser_initbrd alreasy releases resource, do not do it again in fail path in probe function.

2007-02-11[PATCH] Char: mxser_new, alter locking in isrJiri Slaby
Avoid oopsing when stress-testing open/close -- port->tty is NULL sometimes, but is expected to be non-NULL, since dereferencing. Receive/transmit chars iff ASYNC_CLOSING is not set and ASYNC_INITIALIZED is set. Thanks Sergei for pointing this out and testing.

2007-02-11[PATCH] Char: isicom, remove tty_{hang,wake}up bottomhalvesJiri Slaby
- tty_hangup() itself schedules work, so there is no need to schedule hangup in the driver - tty_wakeup(): it's safe to call it while in atomic, so that its schedule_work might be also wiped out Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Acked-by: Alan Cox <alan@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-02-11[PATCH] vt: refactor console SAK processingEric W. Biederman
This does several things. - It moves looking up of the current foreground console into process context where we can safely take the semaphore that protects this operation. - It uses the new flavor of work queue processing. - This generates a factor of do_SAK, __do_SAK that runs immediately. - This calls __do_SAK with the console semaphore held ensuring nothing else happens to the console while we process the SAK operation. - With the console SAK processing moved into process context this patch removes the xchg operations that I used to attempt to attomically update struct pid, because of the strange locking used in the SAK processing. With SAK using the normal console semaphore nothing special is needed. Cc: Oleg Nesterov <oleg@tv-sign.ru> Signed-off-by: Eric W.

Change SysRq showBlockedTasks from sysrq-X to sysrq-W and show that in the Help message. It was previously done via X, but X is already used for Xmon on ppc & powerpc platforms and this collision needs to be avoided. All callers of register_sysrq_key() are now marked in the sysrq op/key table. I didn't mark 'h' as Help because Help is just printed for any unknown key, such as '?'.
