[PATCH v7 0/1] kasan: Avoid sleepable page allocation from atomic context

Posted by Alexander Gordeev 9 months ago

Hi All,

Chages since v6:
- do not unnecessary free pages across iterations

Chages since v5:
- full error message included into commit description

Chages since v4:
- unused pages leak is avoided

Chages since v3:
- pfn_to_virt() changed to page_to_virt() due to compile error

Chages since v2:
- page allocation moved out of the atomic context

Chages since v1:
- Fixes: and -stable tags added to the patch description

Thanks!
