In this round, we've added two features: 1) F2FS_IOC_START_ATOMIC_REPLACE and 2) per-block age-based extent cache. 1) is a variant of the previous atomic write feature which guarantees a per-file atomicity. It would be more efficient than AtomicFile implementation in Android framework. 2) implements another type of extent cache in memory which keeps the per-block age in a file, so that block allocator could split the hot and cold data blocks more accurately. Enhancement: - introduce F2FS_IOC_START_ATOMIC_REPLACE - refactor extent_cache to add a new per-block-age-based extent cache support - introduce discard_urgent_util, gc_mode, max_ordered_discard sysfs knobs - add proc entry to show discard_plist info - optimize iteration over sparse directories - add barrier mount option Bug fix - avoid victim selection from previous victim section - fix to enable compress for newly created file if extension matches - set zstd compress level correctly - initialize locks early in f2fs_fill_super() to fix bugs reported by syzbot - correct i_size change for atomic writes - allow to read node block after shutdown - allow to set compression for inlined file - fix gc mode when gc_urgent_high_remaining is 1 - should put a page when checking the summary info Minor fixes and various clean-ups in GC, discard, debugfs, sysfs, and doc. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAmOaTNUACgkQQBSofoJI UNIQnw//V7Q8DUHw5YNj04jutwXH2DNMLAmn/NJh5S6dIzy/LiywlSzVg53/0/FP 4K577urUkIhgilRO+yncUMSnSQk7BluQvGSx4ja2AV+dpDomjxM3GwIacGzSvr7D VfVf8Vig10UEFrrtEEKtv1VFlYHAmo8lLpubzrZHV8aZFLHHYO2fakQhPu8BYsaz eGCJwxjvTZcQUPkaeG9tWto3ChI3F6PzreiQ5TztHhLWSEgw/o0qijpsc+2SthaV my7uGjeBY8EGPeSYbeCxRtdx8g8Qu11K3ISuDj8zBybmjG3IWOGt1CVcrY6tZbal aL70CMtHkMqMn03VqbpCTqBtdWNMrrw5sYSL3qXIUdXlX/2yJBh9fLAeNxKNs5Nu 6veSb2WgYMHqIsClkAAcP0xJ8g6kodGoG60wVr4ek0Vdt4osaQqwq+bnffpwwxtQ F+7aRuinv+rdrHJ4CuFXAmHPKh2lBe2lTTWZEKg2RptTxZ5DhD2Qn6x1khPD2GFA mG2Aeiq6PVxxEeIO+w/VBCuAgpGTFV2N/ZIF8VfjFNdWiN5OGLWQNHC2KGj2G2uV +fA+B91txQWtjY9h72YJb2+aGIixcnLY24ni4mDgDItqtpCB4PW56W8cbnbv9Pl+ aXAWdADqJdDyllHoVB/JQ24gr2fATJGRIDeYDnw+vPP4f5ZT5vg= =f00t -----END PGP SIGNATURE----- Merge tag 'f2fs-for-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've added two features: F2FS_IOC_START_ATOMIC_REPLACE and a per-block age-based extent cache.
