vfs: forbid write access when reading a file into memory
This patch is based on top of the "vfs: support for a common kernel file loader" patch set. In general when the kernel is reading a file into memory it does not want anything else writing to it. The kernel currently only forbids write access to a file being executed. This patch extends this locking to files being read by the kernel.
