[PATCH] crash: memory.c handling of node_online_map

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 





This patch enables finding of node_states (instead of node_online_map)
when using a kerntypes file for a namelist.

I tested this against the dump of a 2.6.26 kernel.

Diffed against crash-4.0-7.1
