[PATCH 5/5] zram: use generic PAGE_SECTORS and PAGE_SECTORS_SHIFT

Luis Chamberlain
2023-04-21T19:58:34Z

Instead of re-defining the already existing constants use the provided ones:

So replace:

o SECTORS_PER_PAGE_SHIFT with PAGE_SECTORS_SHIFT
o SECTORS_PER_PAGE with PAGE_SECTORS

This produces no functional changes.
