The root cause is there will be race condition in between f2fs_ioc_fitrim()
and f2fs_remount():
- f2fs_remount - f2fs_ioc_fitrim
- f2fs_issue_discard_timeout
- __issue_discard_cmd
- __drop_discard_cmd
- __wait_all_discard_cmd
- f2fs_trim_fs
- f2fs_write_checkpoint
- f2fs_clear_prefree_segments
- f2fs_issue_discard
- __issue_discard_async
- __queue_discard_cmd
- __update_discard_tree_range
- __insert_discard_cmd
- __create_discard_cmd
: atomic_inc(&dcc->discard_cmd_cnt);
- sanity check on dcc->discard_cmd_cnt (expect discard_cmd_cnt to be zero)
This will only happen when fitrim races w/ remount rw, if we remount to
readonly filesystem, remount will wait until mnt_pcp.mnt_writers to zero,
that means fitrim is not in process at that time.

options in f2fs_fill_super is alloc by kstrdup:
options = kstrdup((const char *)data, GFP_KERNEL)
sit_bitmap[_mir], nat_bitmap[_mir] are alloc by kmemdup:
sit_i->sit_bitmap = kmemdup(src_bitmap, sit_bitmap_size, GFP_KERNEL);

write_io is alloc by f2fs_kmalloc:
sbi->write_io[i] = f2fs_kmalloc(sbi,
array_size(n, sizeof(struct f2fs_bio_info))
Use kfree is more efficient.
