As discuss with Jaegeuk and Chao, "Once checkpoint is done, f2fs doesn't need to update there-in filename at all." The disk-level filename is used only one case, 1. create a file A under a dir 2. sync A 3. godown 4. umount 5. mount (roll_forward) Only the rename/cross_rename changes the filename, if it happens, a. between step 1 and 2, the sync A will caused checkpoint, so that, the roll_forward at step 5 never happens. b. after step 2, the roll_forward happens, file A will roll forward to the result as after step 1. So that, any updating the disk filename is useless, just cleanup it.

Pull GPIO fixes from Linus Walleij: "Here is the first set of GPIO fixes for 4.11. It was delayed a bit beacuse I was chicken when linux-next was not rotating last week. This hits the ST serial driver in drivers/tty/serial and that has an ACK from Greg, he suggested to keep the old GPIO fwnode API around to smoothen things in the merge Windod and those have now served their purpose so we take them out and convert the last driver to the new API. Apart from that it's fixes as usual. Summary: - set the parent on the Altera A10SR driver, also fix high level IRQs. - fix error path on the mockup driver. - compilation noise about unused functions fixed. - fix missed interrupts on the MCP23S08 expander, this is also tagged for stable. - retire the interrim helpers devm_get_gpiod_from_child() used to smoothen merging in the merge window" * tag 'gpio-v4.11-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: gpio:mcp23s08 Fixed missing interrupts serial: st-asc: Use new GPIOD API to obtain RTS pin gpio: altera: Use handle_level_irq when configured as a level_high gpio: xgene: mark PM functions as __maybe_unused gpio: mockup: return -EFAULT if copy_from_user() fails gpio: altera-a10sr: Set gpio_chip parent property
