Jerome Marchand 924bd88d70 Staging: zram: allow partial page operations ... Commit 7b19b8d45b (zram: Prevent overflow in logical block size) introduced ZRAM_LOGICAL_BLOCK_SIZE constant to prevent overflow of logical block size on 64k page kernel. However, the current implementation of zram only allow operation on block of the same size as a page. That makes theorically legit 4k requests fail on 64k page kernel. This patch makes zram allow operation on partial pages. Basically, it means we still do operations on full pages internally, but only copy the relevent segments from/to the user memory.
