f2fs: fix to account gc stats correctly
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")
