From: Matias Bjørling <mb@xxxxxxxxxxx> [ Upstream commit 8bbd45d02a118cbefdf4e1a6274bd965a6aa3c59 ] The calculation of pblk->min_write_pgs should only use the optimal write size attribute provided by the drive, it does not correlate to the memory page size of the system, which can be smaller or larger than the LBA size reported.
