libata-scsi: avoid repeated calculation of number of TRIM ranges Currently libata statically allows only 1-block (512-byte) payload for each TRIM command. Each payload can carry 64 TRIM ranges since each range requires 8 bytes. It is silly to keep doing the calculation (512 / 8) in different places. Hence, define the new ATA_MAX_TRIM_RNUM for the result. Signed-off-by: Tom Yan <tom.ty89@gmail.com> Signed-off-by: Tejun Heo <tj@kernel.org>
