f2fs: fix to account dirty data in __get_secs_required()

2024-12-05T13:02:20Z

[ Upstream commit 1acd73edbbfef2c3c5b43cba4006a7797eca7050 ] It will trigger system panic w/ testcase in [1]: ------------[ cut here ]------------ kernel BUG at fs/f2fs/segment.c:2752! RIP: 0010:new_curseg+0xc81/0x2110 Call Trace: f2fs_allocate_data_block+0x1c91/0x4540 do_write_page+0x163/0xdf0 f2fs_outplace_write_data+0x1aa/0x340 f2fs_do_write_data_page+0x797/0x2280 f2fs_write_single_data_page+0x16cd/0x2190 f2fs_write_cache_pages+0x994/0x1c80 f2fs_write_data_pages+0x9cc/0xea0 do_writepages+0x194/0x7a0 filemap_fdatawrite_wbc+0x12b/0x1a0 __filemap_fdatawrite_range+0xbb/0xf0 file_write_and_wait_range+0xa1/0x110 f2fs_do_sync_file+0x26f/0x1c50 f2fs_sync_file+0x12b/0x1d0 vfs_fsync_range+0xfa/0x230 do_fsync+0x3d/0x80 __x64_sys_fsync+0x37/0x50 x64_sys_call+0x1e88/0x20d0 do_syscall_64+0x4b/0x110 entry_SYSCALL_64_after_hwframe+0x76/0x7e The root cause is if checkpoint_disabling and lfs_mode are both on, it will trigger OPU for all overwritten data, it may cost more free segment than expected, so f2fs must account those data correctly to calculate cosumed free segments later, and return ENOSPC earlier to avoid run out of free segment during block allocation.

f2fs: add valid block ratio not to do excessive GC for one time GC

2024-09-11T03:33:08Z

We need to introduce a valid block ratio threshold not to trigger excessive GC for zoned deivces. The initial value of it is 95%. So, F2FS will stop the thread from intiating GC for sections having valid blocks exceeding the ratio. Signed-off-by: Daeho Jeong Reviewed-by: Chao Yu Signed-off-by: Jaegeuk Kim

f2fs: fix start segno of large section

2024-07-09T19:33:50Z

get_ckpt_valid_blocks() checks valid ckpt blocks in current section. It counts all vblocks from the first to the last segment in the large section. However, START_SEGNO() is used to get the first segno in an SIT block. This patch fixes that to get the correct start segno.
