f2fs-for-4.21-rc1
In this round, we've focused on bug fixes since Pixel devices have been shipping with f2fs. Some of them were related to hardware encryption support which are actually not an issue in mainline, but would be better to merge them in order to avoid potential bugs. Enhancement: - do GC sub-sections when the section is large - add a flag in ioctl(SHUTDOWN) to trigger fsck for QA - use kvmalloc() in order to give another chance to avoid ENOMEM Bug fix: - fix accessing memory boundaries in a malformed iamge - GC gives stale unencrypted block - GC counts in large sections - detect idle time more precisely - block allocation of DIO writes - race conditions between write_begin and write_checkpoint - allow GCs for node segments via ioctl() There are various clean-ups and minor bug fixes as well. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAlwmkzcACgkQQBSofoJI UNLIlw//RUd8rH8VMW/BcXQ3fwB8qFCk296cIVlWQu12BV7vmMKY886Sc+C9uAuR 9Lze4D6Iyg1k2KLkaWKhnE2E4ZWQ2O5zVf11r4amm1bN9glPJAKfLWbenJhMfeGa IdWo1ksntxgjfqLim2QlGSv5cBUjEo8zf32D446BbQURQMD/mm/lndywItS5vTx1 2eGKJ3pSXX6geFzyf1pD/wmC/7j6roKaTKAIMBagIuINNukeHctT/gRfklmYmOFC lRbXlsYhjIfGln6gktY6r4qyZbouOMad2fDl+dkp+UewQM4/2xLUaMqiN2eqd7Hr cag9LGe80MGgWwesqS6VOJHQviOlNd78Ie//iO1+ZsaIxKrvgzocRSDdxZswv+Vq reZNsEKH0s4/0ik9hiprW1NdQLvtg7e/UWPyrRvVRlDVitW/BXOWRBpGVgkdg01K OmAxNrVcr2+Gxp8jZL7M+rQdpApL/ms31x9HE/8u5ABBZfmCy3zhpICTZ6Hdngp1 3iUi2PvKUg+Y7KgII1nK2HLDpmZZ5UkLm8NhxLI0ntBWExjQjOBasOxPJf4en/UR TAtK3ozNKim3fQ01NCBy3B8WMKRtovxLK6PgqNPROJparlKJ3FEHnPIrYKglDUPg sxWCm1gFSraRGP86TaeGeD+v+PP6erI9CTaf6F/U3pWFgIpHoPg= =NEns -----END PGP SIGNATURE----- Merge tag 'f2fs-for-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've focused on bug fixes since Pixel devices have been shipping with f2fs.
