This patch supports to recognize hot file extension in f2fs, so that we can allocate proper hot segment location for its data, which can lead to better hot/cold seperation in filesystem. In addition, we changes a bit on query/add/del operation method for extension_list sysfs entry as below: - Query: cat /sys/fs/f2fs/<disk>/extension_list - Add: echo 'extension' > /sys/fs/f2fs/<disk>/extension_list - Del: echo '!extension' > /sys/fs/f2fs/<disk>/extension_list - Add: echo '[h/c]extension' > /sys/fs/f2fs/<disk>/extension_list - Del: echo '[h/c]!extension' > /sys/fs/f2fs/<disk>/extension_list - [h] means add/del hot file extension - [c] means add/del cold file extension Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

Sqlite user Background GC - move_data_block : move page #1 - f2fs_is_atomic_file - f2fs_ioc_start_atomic_write - f2fs_ioc_commit_atomic_write - commit_inmem_pages : commit page #1 & set node #2 dirty - f2fs_submit_page_write - f2fs_update_data_blkaddr - set_page_dirty : set node #2 dirty - f2fs_do_sync_file - fsync_node_pages : commit node #1 & node #2, then sudden power-cut In a race case, we may check FI_ATOMIC_FILE flag before starting atomic write flow, then we will commit meta data before data with reversed order, after a sudden pow-cut, database transaction will be inconsistent. So we'd better to exclude gc/atomic_write to each other by using lock instead of flag checking. Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

This patch adds an mount option, "alloc_mode=%s" having two options, "default" and "reuse". In "alloc_mode=reuse" case, f2fs starts to allocate segments from 0'th segment all the time to reassign segments. It'd be useful for small-sized eMMC parts.

As Jayashree Mohan reported: A simple workload to reproduce this would be : 1. create foo 2. Write (8K - 16K) // foo size = 16K now 3. fsync() 4. falloc zero_range , keep_size (4202496 - 4210688) // foo size must be 16K 5. fdatasync() Crash now On recovery, we see that the file size is 4210688 and not 16K, which violates the semantics of keep_size flag. We have a test case to reproduce this using CrashMonkey on 4.15 kernel. Try this out by simply running : ./c_harness -f /dev/sda -d /dev/cow_ram0 -t f2fs -e 102400 -P -v tests/generic_468_zero.so The root cause is that we miss to set KEEP_SIZE bit correctly in zero_range when zeroing block cross EOF with FALLOC_FL_KEEP_SIZE, let's fix this missing case.

Previous dentry page uses highmem, which will cause panic in platforms using highmem (such as arm), since the address space of dentry pages from highmem directly goes into the decryption path via the function fscrypt_fname_disk_to_usr. But sg_init_one assumes the address is not from highmem, and then cause panic since it doesn't call kmap_high but kunmap_high is triggered at the end. To fix this problem in a simple way, this patch avoids to put dentry page in pagecache into highmem.
