Subject: kernel: disable cfi cmdset 0002 erase suspend
|
||||
|
||||
on some platforms, erase suspend leads to data corruption and lockups when write
|
||||
ops collide with erase ops. this has been observed on the buffalo wzr-hp-g300nh.
|
||||
rather than play whack-a-mole with a hard to reproduce issue on a variety of devices,
|
||||
simply disable erase suspend, as it will usually not produce any useful gain on
|
||||
the small filesystems used on embedded hardware.
