Subject: [PATCH for-4.9 0/3] Improvements to ERR_PTR() infrastructure
Date: Tue, 1 Nov 2016 10:46:07 +0000 [thread overview]
Message-ID: <1477997170-7795-1-git-send-email-andrew.cooper3@citrix.com> (raw)
One XenServer issue I am looking in to requires improvements to the memory
allocation logic, mostly to avoid losing error information internally.
As a result, I am choosing to make these ERR_PTR() improvements a prerequisite
to avoid accidentally introducing further issues.
Andrew Cooper (3):
xen/err: Use static inlines and boolean types
xen/err: Support an optional per-arch slide for the error region
xen/x86: Use non-canonical pointers for ERR_PTR() errors
xen/arch/x86/Kconfig | 18 ++++++++++++++++++
xen/include/asm-x86/config.h | 8 ++++++++
xen/include/xen/err.h | 23 ++++++++++++++++++-----
