[v2 0/1] discard memblock data later

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

 



Changelog:
v1 - v2
        - Removed debugging change to INIT_MEMBLOCK_REGIONS

This fixes a problem with use after free that can happen when there are
many physical regions and deferred pages are enabled.

Also, this fix is needed for my upcoming improvements to deferred pages:
"complete deferred page initialization", where we do not zero the backing
struct page memory.
