The attached files are respectively: - a kernel module which implements 4 pseudo-devices with different aio_read/aio_write methods: - aiotest0 simply returns -EIOCBQUEUED; - aiotest1 sets ki_cancel method and returns -EIOCBQUEUED; - aiotest2 sets KIF_CANCELLED flag and returns -EINTR; - aiotest3 sets... 27 May 2010 19:16

[PATCH] panic: keep blinking in spite of long spin timer mode
To keep panic_timeout accuracy when running under a hypervisor, the current implementation only spins on long time (1 second) calls to mdelay. That brings a good effect, but we must give up blinking even if we have a panic_blink. This patch keeps blinking in spite of long spin timer mode. We now have new kern... 27 May 2010 19:16

[PATCH] hugetlb: call mmu notifiers on hugepage cow
From: Doug Doan <dougd(a)cray.com> When a copy-on-write occurs, we take one of two paths in handle_mm_fault: through handle_pte_fault for normal pages, or through hugetlb_fault for huge pages. In the normal page case, we eventually get to do_wp_page and call mmu notifiers via ptep_clear_flush_notify. There is n... 27 May 2010 19:16
