The new notify_handler logic determining if autorelease should be used or not is a bit awkward, and can result in more than one call to sparse_keymap_report_event for the same event (scancode). The nesting and long lines also made it difficult to read. Simplify the logic by eliminating a level of nesting with a goto and always calculate autorelease and val so we can make a single call to sparse_keymap_report_event.

The Lenovo Helix 2 and Dell XPS 12 (9Q33) have an extra button on the front showing a 'Windows' logo, both reporting event codes 0xC2/0xC3 on press/release. On the Dell, both press/release are distinct events while on the Helix 2 both events are generated on release.

Currently all key events use autorelease, but this forbids use as a modifier key. As all event codes come in even/odd pairs, we can lookup the key type (KE_KEY/KE_IGNORE) for the key up event corresponding to the currently handled key down event. If the key up is ignored, we keep setting the autorelease flag for the key down.

Suspend with shallow wakes is not a useful parameter since the phenomena does not exist on deployed devices and is only a parameter of use during device power-on phase. The field always reads zero. Additionally there are other easier methods to detect it, e.g., if the S0ix counter increments by more than one during suspend. Hence the field is superfluous and can be removed. This patch also slightly renames the S0ix total field for better viewability.

Suspend stats are not reported consistently due to a limitation in the PMC firmware. This limitation causes a delay in updating the s0ix counters and residencies in the telemetry log upon s0ix exit. As a consequence, reading these counters from the suspend-exit notifier may result in zero read. This patch fixes this issue by cross-verifying the s0ix residencies from the GCR TELEM registers in case the counters are not incremented in the telemetry log after suspend.

Make afs_write_begin() wait for a page that's marked PG_writeback because: (1) We need to avoid interference with the data being stored so that the data on the server ends up in a defined state. (2) page->private is used to track the window of dirty data within a page, but it's also used by the storage code to track what's being written, being cleared by the completion notification. Ownership can't be relinquished by the storage code until completion because it a store fails, the data must be remarked dirty. Tracing shows something like the following (edited): x86_64-linux-gn-15940 [1] afs_page_dirty: vn=ffff8800bef33800 9c75 begin 0-125 kworker/u8:3-114 [2] afs_page_dirty: vn=ffff8800bef33800 9c75 store+ 0-125 x86_64-linux-gn-15940 [1] afs_page_dirty: vn=ffff8800bef33800 9c75 begin 0-2052 kworker/u8:3-114 [2] afs_page_dirty: vn=ffff8800bef33800 9c75 clear 0-2052 kworker/u8:3-114 [2] afs_page_dirty: vn=ffff8800bef33800 9c75 store 0-0 kworker/u8:3-114 [2] afs_page_dirty: vn=ffff8800bef33800 9c75 WARN 0-0 The clear (completion) corresponding to the store+ (store continuation from a previous page) happens between the second begin (afs_write_begin) and the store corresponding to that.

The recent conversion of the task state recording to use task_state_index() broke the sched_switch tracepoint task state output. task_state_index() returns surprisingly an index (0-7) which is then printed with __print_flags() applying bitmasks. Not really working and resulting in weird states like 'prev_state=t' instead of 'prev_state=I'. Use TASK_REPORT_MAX instead of TASK_STATE_MAX to report preemption. Build a bitmask from the return value of task_state_index() and store it in entry->prev_state, which makes __print_flags() work as expected.
