2021-04-13USB: serial: ti_usb_3410_5052: drop drain delay for 3410Johan Hovold
Unlike the TUSB5052, the TUSB3410 has an LSR TEMT bit to tell if both the transmitter data and shift registers are empty. Make sure to check also the shift register on TUSB3410 when waiting for the transmit buffer to drain during close and drop the time-based one-char delay which is otherwise needed (e.g. 90 ms at 110 bps).

2021-04-13USB: serial: ti_usb_3410_5052: reduce drain delay to one charJohan Hovold
The three-character drain delay was added by commit f1175daa5312 ("USB: ti_usb_3410_5052: kill custom closing_wait") when removing the custom closing-wait implementation, which used a fixed 20 ms poll period and drain delay. This was likely a bit too conservative as a one-character timeout (e.g. 33 ms at 300 bps) should be enough to compensate for the lack of a transmitter empty bit in the TUSB5052 line-status register.

2021-04-13USB: serial: f81232: drop time-based drain delayJohan Hovold
The f81232 driver now waits for the transmit FIFO to drain during close so there is no need to keep the time-based drain delay, which would add up to two seconds on every close for low line speeds.

It's changing where and how the superblock is stored in the zoned mode. It is an on-disk format change but so far there are no implications for users as the proper mkfs support hasn't been merged and is waiting for the kernel side to settle. Until now, the superblocks were derived from the zone index, but zone size can differ per device. This is changed to be based on fixed offset values, to make it independent of the device zone size. The work on that got a bit delayed, we discussed the exact locations to support potential device sizes and usecases. (Partially delayed also due to my vacation.) Having that in the same release where the zoned mode is declared usable is highly desired, there are userspace projects that need to be updated to recognize the feature. Pushing that to the next release would make things harder to test" * tag 'for-5.12-rc6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: btrfs: zoned: move superblock logging zone location
