2011-08-01oom: task->mm == NULL doesn't mean the memory was freedOleg Nesterov1-1/+3
exit_mm() sets ->mm == NULL then it does mmput()->exit_mmap() which frees the memory. However select_bad_process() checks ->mm != NULL before TIF_MEMDIE, so it continues to kill other tasks even if we have the oom-killed task freeing its memory. Change select_bad_process() to check ->mm after TIF_MEMDIE, but skip the tasks which have already passed exit_notify() to ensure a zombie with TIF_MEMDIE set can't block oom-killer. Alternatively we could probably clear TIF_MEMDIE after exit_mmap().

2011-08-01drm/i915/dp: wait for previous AUX channel activity to clearJesse Barnes1-3/+11
Before initiating a new read or write on the DP AUX channel, wait for any outstanding activity to complete. This may happen during normal retry behavior. If the wait fails (i.e. after 1ms the AUX channel is still busy) dump a backtrace to make the caller easier to spot. v2: use msleep instead, and timeout after 3ms (only ever saw 1 retry with msleep in testing) v3: fix backtrace check to trigger if the 3ms wait times out Fixes https://bugs.freedesktop.org/show_bug.cgi?id=38136.

an 'unhandled fault' is causes when a gadget driver calls usb_gadget_connect() while the USB cable isn't plugged into the OTG port. the fault is caused by an access to MUSB's memory space while its clock is turned off due to pm_runtime kicking in. in order to fix the fault, we enclose musb_gadget_pullup() with pm_runtime_get_sync() ... pm_runtime_put() calls to be sure we will always reach that path with clock turned on.

Essentially, the patch changes the hid gadget such that a request for the HID descriptor is handled by copying the descriptor into the response buffer, rather than falling through the default case, in which the request is answered by a STALL.

2011-08-01Btrfs: don't print the leaf if we had an errorJosef Bacik1-1/+3
In __btrfs_free_extent we will print the leaf if we fail to find the extent we wanted, but the problem is if we get an error we won't have a leaf so often this leads to a NULL pointer dereference and we lose the error that actually occurred. So only print the leaf if ret > 0, which means we didn't find the item we were looking for but we didn't error either. This way the error is preserved.
