f2fs: fix to account cp stats correctly

2023-09-13T07:48:33+00:00

[ Upstream commit eb61c2cca2eb2110cc7b61a7bc15b3850977a778 ] cp_foreground_calls sysfs entry shows total CP call count rather than foreground CP call count, fix it. Fixes: fc7100ea2a52 ("f2fs: Add f2fs stats to sysfs") Signed-off-by: Chao Yu Signed-off-by: Jaegeuk Kim Signed-off-by: Sasha Levin

f2fs: fix to account gc stats correctly

2023-09-13T07:48:32+00:00

[ Upstream commit 9bf1dcbdfdc8892d9cfeaeab02519c0ecf17fe51 ] As reported, status debugfs entry shows inconsistent GC stats as below: GC calls: 6008 (BG: 6161) - data segments : 3053 (BG: 3053) - node segments : 2955 (BG: 2955) Total GC calls is larger than BGGC calls, the reason is: - f2fs_stat_info.call_count accounts total migrated section count by f2fs_gc() - f2fs_stat_info.bg_gc accounts total call times of f2fs_gc() from background gc_thread Another issue is gc_foreground_calls sysfs entry shows total GC call count rather than FGGC call count. This patch changes as below for fix: - account GC calls and migrated segment count separately - support to account migrated section count if it enables large section mode - fix to show correct value in gc_foreground_calls sysfs entry Fixes: fc7100ea2a52 ("f2fs: Add f2fs stats to sysfs") Signed-off-by: Chao Yu Signed-off-by: Jaegeuk Kim Signed-off-by: Sasha Levin

f2fs: allocate node blocks for atomic write block replacement

f2fs: fix to check return value of inc_valid_block_count()

2023-04-13T23:37:57+00:00

In __replace_atomic_write_block(), we missed to check return value of inc_valid_block_count(), for extreme testcase that f2fs image is run out of space, it may cause inconsistent status in between SIT table and total valid block count.

f2fs: remove struct victim_selection default_v_ops

2023-04-10T17:58:44+00:00

There is only single instance of these ops, and Jaegeuk point out that: Originally this was intended to give a chance to provide other allocation option. Anyway, it seems quit hard to do it anymore. So remove the indirection and call f2fs_get_victim() directly. Signed-off-by: Yangtao Li Reviewed-by: Chao Yu Signed-off-by: Jaegeuk Kim
