Re: [PATCH] LoongArch: make the users of larch_insn_gen_break() constant

[PATCH] vhost-vdpa: switch to use vmf_insert_pfn() in the fault handler

remap_pfn_page() should not be called in the fault handler as it may change the vma->flags which may trigger lockdep warning since the vma write lock is not held. Actually there's no need to modify the vma->flags as it has been set in the mmap(). So this patch switches to use vmf_insert_pfn() inste

[PATCH] uapi: change TRACE_MMAP_IOCTL_GET_READER to avoid collision with TCGETS

The number that was initially chosen for TRACE_MMAP_IOCTL_GET_READER, unfortunately, collides with TCGETS on most of architectures. For example, this is how strace output would look like when support for this value of TRACE_MMAP_IOCTL_GET_READER is added: $ strace -e ioctl stty ioctl(0, TCGETS or
