* [PATCH] n_r3964: Use struct pid to track user space clientsEric W. Biederman2006-12-131-20/+17
| | | | | | | | | | | | | | Currently this driver tracks user space clients it should send signals to. In the presenct of file descriptor passing this is appears susceptible to confusion from pid wrap around issues. Replacing this with a struct pid prevents us from getting confused, and prepares for a pid namespace implementation. Signed-off-by: Eric W.

* [PATCH] rtc framewok: rtc_wkalrm.enabled reporting updatesDavid Brownell2006-12-135-12/+8
| | | | | | | | | | | | | | | | Fix a glitch in the procfs dumping of whether the alarm IRQ is enabled: use the traditional name (from drivers/char/rtc.c and many other places) of "alarm_IRQ", not "alrm_wakeup" (which didn't even match the efirtc code, which originated that reporting API). Also, update a few of the RTC drivers to stop providing that duplicate status, and/or to expose it properly when reporting the alarm state. We really don't want every RTC driver doing their own thing here...

* [PATCH] RTC driver init adjustmentJan Beulich2006-12-131-15/+17
| | | | | | | | | | | | | | | | - conditionalizes procfs code upon CONFIG_PROC_FS (to reduce code size when that option is not enabled) - make initialization no longer fail when the procfs entry can't be allocated (namely would initialization always have failed when CONFIG_PROC_FS was not set) - move the formerly file-scope static variable rtc_int_handler_ptr into the only function using it, and makes it automatic.

| | | | | | | | | | | | | | | | | Remove calls to pci_disable_device except in fail_all_cmds. The pci_disable_device function does something nasty to Smart Array controllers that pci_enable_device does not undo. So if the driver is unloaded it cannot be reloaded. Also, customers can disable any pci device via the ROM Based Setup Utility (RBSU). If the customer has disabled the controller we should not try to blindly enable the card from the driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During connection establishment, the passive side of a connection can receive messages from the active side before the connection event has been delivered to the user. Allow the passive side to send messages in response to received data before the event is delivered. To handle the case where the connection messages are lost, a new rdma_notify() function is added that users may invoke to force a connection into the established state.
