- n_tty: Fix buffer overruns with larger-than-4k pastes
-
- readline() inadvertently triggers an error recovery path when
- pastes larger than 4k overrun the line discipline buffer. The
- error recovery path discards input when the line discipline buffer
- is full and operating in canonical mode and no newline has been
- received. Because readline() changes the termios to non-canonical
- mode to read the line char-by-char, the line discipline buffer
- can become full, and then when readline() restores termios back
- to canonical mode for the caller, the now-full line discipline
- buffer triggers the error recovery.
-
- When changing termios from non-canon to canon mode and the read
- buffer contains data, simulate an EOF push _without_ the
- DISABLED_CHAR in the read buffer.
-
- Importantly for the readline() problem, the termios can be
- changed back to non-canonical mode without changes to the read
- buffer occurring; ie., as if the previous termios change had not
- happened (as long as no intervening read took place).
-
- Preserve existing userspace behavior which allows '\0's already
- received in non-canon mode to be read as '\0's in canon mode
- (rather than trigger add'l EOF pushes or an actual EOF).
-
- Patch based on original proposal and discussion here

-Subject: ACPI / EC: Clear stale EC events on Samsung systems
-
-A number of Samsung notebooks (530Uxx/535Uxx/540Uxx/550Pxx/900Xxx/etc)
-continue to log events during sleep (lid open/close, AC plug/unplug,
-battery level change), which accumulate in the EC until a buffer fills.
-After the buffer is full (tests suggest it holds 8 events), GPEs stop
-being triggered for new events. This state persists on wake or even on
-power cycle, and prevents new events from being registered until the EC
-is manually polled.
-
-This is the root cause of a number of bugs, including AC not being
-detected properly, lid close not triggering suspend, and low ambient
-light not triggering the keyboard backlight. The bug also seemed to be
-responsible for performance issues on at least one user's machine.
-
-Juan Manuel Cabo found the cause of bug and the workaround of polling
-the EC manually on wake.
+
+--
+2.20.1
-The loop which clears the stale events is based on an earlier patch by
-Lan Tianyu (see referenced attachment).
-This patch:
- - Adds a function acpi_ec_clear() which polls the EC for stale _Q
- events at most ACPI_EC_CLEAR_MAX (currently 100) times. A warning is
- logged if this limit is reached.
- - Adds a flag EC_FLAGS_CLEAR_ON_RESUME which is set to 1 if the DMI
- system vendor is Samsung. This check could be replaced by several
- more specific DMI vendor/product pairs, but it's likely that the bug
- affects more Samsung products than just the five series mentioned
- above. Further, it should not be harmful to run acpi_ec_clear() on
- systems without the bug; it will return immediately after finding no
- data waiting.
- - Runs acpi_ec_clear() on initialisation (boot), from acpi_ec_add()
- - Runs acpi_ec_clear() on wake, from acpi_ec_unblock_transactions()
+Link every newly allocated writeback bio to cgroup pointed to by the
+writeback control structure, and charge every byte written back to it.
