H A D | subpage.c | fdf250db Tue Aug 17 04:38:49 CDT 2021 Qu Wenruo <wqu@suse.com> btrfs: subpage: only call btrfs_alloc_subpage() when sectorsize is smaller than PAGE_SIZE
There are two call sites of btrfs_alloc_subpage():
- btrfs_attach_subpage() We have ensured sectorsize is smaller than PAGE_SIZE
- alloc_extent_buffer() We call btrfs_alloc_subpage() unconditionally.
The alloc_extent_buffer() forces us to check the sectorsize size against page size inside btrfs_alloc_subpage().
Since the function name, btrfs_alloc_subpage(), already indicates it should only get called for subpage cases, do the check in alloc_extent_buffer() and add an ASSERT() in btrfs_alloc_subpage().
