Hi Greg,
I sent a backported patch for 4.19-stable in reply to your email. The backport is identical to the one I sent separately for the 5.4-stable tree.
It breaks the build:
drivers/block/null_blk_zoned.c: In function ‘null_zone_init’: drivers/block/null_blk_zoned.c:5:42: error: ‘SZ_1M’ undeclared (first use in this function) 5 | #define MB_TO_SECTS(mb) (((sector_t)mb * SZ_1M) >> SECTOR_SHIFT) | ^~~~~ drivers/block/null_blk_zoned.c:27:23: note: in expansion of macro ‘MB_TO_SECTS’ 27 | dev_capacity_sects = MB_TO_SECTS(dev->size); | ^~~~~~~~~~~ drivers/block/null_blk_zoned.c:5:42: note: each undeclared identifier is reported only once for each function it appears in 5 | #define MB_TO_SECTS(mb) (((sector_t)mb * SZ_1M) >> SECTOR_SHIFT) | ^~~~~ drivers/block/null_blk_zoned.c:27:23: note: in expansion of macro ‘MB_TO_SECTS’ 27 | dev_capacity_sects = MB_TO_SECTS(dev->size); | ^~~~~~~~~~~
