[PATCH v3 0/4] block: simplify with PAGE_SECTORS_SHIFT

[Luis Chamberlain]

Just spinning these low hanging fruit patches I forgot about.

Changes on v3:

 o Add tags for Reviews/acks
 o rebase onto next-20230914
 o Fixes as suggested by Johannes Thumshirn:
   - drop not-needed parens on dm bufio
   - use SECTOR_MASK instead of PAGE_SECTORS - 1 for the zram driver
 o Drop shmem patches as they are already merged / modified

Changes on v2:
                                                                                                                                                                                              
 o keep iomap math visibly simple                                                                                                                                                             
 o Add tags for Reviews/acks                                                                                                                                                                  
 o rebase onto next-20230525 

Luis Chamberlain (4):
  drbd: use PAGE_SECTORS_SHIFT and PAGE_SECTORS
