Ritesh Harjani (IBM) 147d4a092e jbd2: Remove page size assumptions ... jbd2_alloc() allocates a buffer from slab when the block size is smaller than PAGE_SIZE, and slab may be using a compound page. Before commit 8147c4c454, we set b_page to the precise page containing the buffer and this code worked well. Now we set b_page to the head page of the allocation, so we can no longer use offset_in_page(). While we could do a 1:1 replacement with offset_in_folio(), use the more idiomatic bh_offset() and the folio APIs to map the buffer. This isn't enough to support a b_size larger than PAGE_SIZE on HIGHMEM machines, but this is good enough to fix the actual bug we're seeing.
