The GRU TLB miss handler walks a process’s page tables without holding
\npage-table locks or a reference to the mapped page. It also uses a kernel
\npage-table accessor on user page tables and supports only PMD-level large
\nmappings on x86-64.<\/p>\n
Remove the direct walker. Send interrupt faults directly to user polling
\nmode so the existing call-OS fallback retries them in process context.<\/p>\n
Remove the mmap-lock failure statistic that can no longer be incremented.<\/p>\n","protected":false},"excerpt":{"rendered":"
