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.
