Subject: [PATCH] rules: mark hotplugged memory as movable
|
|
|
aed857 |
|
|
|
aed857 |
Otherwise the kernel is free to use to memory block also for storing
|
|
|
aed857 |
non-movable memory (any other memory except anonymous memory allocations
|
|
|
aed857 |
and page cache). If user later wants to hot unplug the memory the kernel
|
|
|
aed857 |
will return error in case that some non-movable memory has been place to
|
|
|
aed857 |
the memory block.
|
|
|
aed857 |
|
|
|
aed857 |
Marking hot plugged memory blocks as movable seems to be better
|
|
|
aed857 |
default. Users with specific needs are free to override this udev rule.
