Andreas Kling a7d193951f Kernel: Don't hog file system lock when doing BlockBasedFileSystem I/O ...

The file system lock is meant to protect the file system metadata
(super blocks, bitmaps, etc.) Not protect processes from reading
independent parts of the disk at once.

This patch introduces a new lock to protect the *block cache* instead,
which is the real thing that needs synchronization.
