The constant ATA_SHT_USE_CLUSTERING in include/linux/libata.h controls
the use of SCSI layer's use_clustering feature, for a great many libata
drivers.
The current setup has clustering disabled, which in theory causes the
block layer to do less work, at the expense of a greater number of
scatter/gather table entries used.
Any opinions WRT turning on clustering for libata?
