With the current aio code there is no need for the magic KIOCB_CANCELLED value, as a cancelation just kicks the driver to queue the completion ASAP, with all actual completion handling done in another thread. Given that both the completion path and cancelation take the context lock there is no need

[PATCH 08/32] aio: replace kiocb_set_cancel_fn with a cancel_kiocb file operation

The current kiocb_set_cancel_fn implementation assumes the kiocb is embedded into an aio_kiocb, which is fundamentally unsafe as it might have been submitted by non-aio callers. Instead add a cancel_kiocb file operation that replaced the ki_cancel function pointer set by kiocb_set_cancel_fn, and o

[PATCH 06/32] aio: simplify KIOCB_KEY handling

No need to pass the key field to lookup_iocb to compare it with KIOCB_KEY, as we can do that right after retrieving it from userspace. Also move the KIOCB_KEY definition to aio.c as it is an internal value not used by any other place in the kernel. Signed-off-by: Christoph Hellwig --- fs/aio.c

[PATCH] [stable 4.14] arm64: Add work around for Arm Cortex-A55 Erratum 1024718

commit ece1397cbc89c51914fae1aec729539cfd8bd62b upstream Some variants of the Arm Cortex-55 cores (r0p0, r0p1, r1p0) suffer from an erratum 1024718, which causes incorrect updates when DBM/AP bits in a page table entry is modified without a break-before-make sequence. The work around is to disable
