Subject: [PATCH 0/2] Minor fixups for hugetlb fault path
Date: Thu, 9 May 2024 12:01:46 +0200 [thread overview]
Message-ID: <20240509100148.22384-1-osalvador@suse.de> (raw)
Hi,
this series contains a couple of fixups for hugetlb_fault and hugetlb_wp
respectively, where a VM_FAULT_SET_HINDEX call was missing.
I did not bother with a Fixes tag because the missing piece here is that
we will not report to userspace the right extension of the faulty area
by adjusting struct kernel_siginfo.si_addr_lsb, but I do not consider that
to be a big issue because I assume that userspace already knows the size
of the mapping anyway.
