f2fs: Pass a folio to f2fs_submit_merged_write_cond()

2025-07-22T15:58:05+00:00

Most callers pass NULL, and the one that passes a page already has a
folio.  Also convert __submit_merged_write_cond() to take a folio.

f2fs: Add fio->folio

2025-07-22T15:56:39+00:00

Put fio->page insto a union with fio->folio.  This lets us remove a
lot of folio->page and page->folio conversions.

f2fs: introduce is_cur{seg,sec}()

2025-07-09T18:02:20+00:00

There are redundant codes in IS_CUR{SEG,SEC}() macros, let's introduce
inline is_cur{seg,sec}() functions, and use a loop in it for cleanup.

Meanwhile, it enhances expansibility, as it doesn't need to change
is_cur{seg,sec}() when we add a new log header.

f2fs: use kfree() instead of kvfree() to free some memory

2025-07-09T17:59:39+00:00

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);
	sit_i->sit_bitmap_mir = kmemdup(src_bitmap,
					sit_bitmap_size, GFP_KERNEL);
	nm_i->nat_bitmap = kmemdup(version_bitmap, nm_i->bitmap_size,
					GFP_KERNEL);
	nm_i->nat_bitmap_mir = kmemdup(version_bitmap, nm_i->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.
