![]() In this round, we've improved the compression support especially for Android such as allowing compression for mmap files, replacing the immutable bit with internal bit to prohibits data writes explicitly, and adding a mount option, "compress_cache", to improve random reads. And, we added "readonly" feature to compact the partition w/ compression enabled, which will be useful for Android RO partitions. Enhancement: - support compression for mmap file - use an f2fs flag instead of IMMUTABLE bit for compression - support RO feature w/ extent_cache - fully support swapfile with file pinning - improve atgc tunability - add nocompress extensions to unselect files for compression Bug fix: - fix false alaram on iget failure during GC - fix race condition on global pointers when there are multiple f2fs instances - add MODULE_SOFTDEP for initramfs As usual, we've also cleaned up some places for better code readability. (e.g., sysfs/feature, debugging messages, slab cache name, and docs) -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAmDmAKIACgkQQBSofoJI UNIGGA//XOcQ+BF6t/os55UZFZc2E5F9VDNkKKBw9WIXp2g2/5D8hl+dT7qMFzMA ndZiRl0wEElce1ZqSzrt8TRcbwoDLgguUdD7B70CR2NMZ36kdVDet3BW01SnwhXy JoiLBkdB5VUdK6QMnP7+xE3tvKhEk3FDohpOoaOtmYyPpk8Q7C8n0PX2KADgmepl 6aNi1aJGy+hf6UyhcHlgfKLpndyX6gGJVmoLN+yJF2D9tLALaLHcZgJUBG9ZajNH yLNwiBG7ybcs1TrWan0887Ne3GVXQpWqrBLou3s4b8abTLpYdFBnIPrN00jmu3Hp I/uenkBS4HI5AZgKFrF1i2QiKlBL/+PmQ1fJtraVJj6auhnwHqZGIdTb8c3AbeSJ pKhC3w8W8K6Fs2Awuyc4qlWDdNquAeM0wf5qlD0yLgZO6/KgpXbBDCQIOhhBn2hW 6h6jZ4KJwEuTXEZB39PJ83YXPpzoxoZW4hVZXlAcsgX2s3Ke1R0BrjZ+ff6JeG78 Oj13PCWFbwd+UjS3I2W1R9taBDeuYkyMF7CKl+BtAzkYD1bO+KfO4sfSoR/XLSVx OwB36LFzklNJeJ1koJZw4n/czJQYZTOQgThDPFDNL1m8zpyB5p8MNL7f84cOJ2Yo aU7mpTX/i56bGsO3sr4OyO37MlZTBkyNjMI/sBgouPXYlN3YmHs= =1IHL -----END PGP SIGNATURE----- Merge tag 'f2fs-for-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've improved the compression support especially for Android such as allowing compression for mmap files, replacing the immutable bit with internal bit to prohibits data writes explicitly, and adding a mount option, "compress_cache", to improve random reads.
