[PATCH 0/3] Improve the mmap() emulation on Windows

[Johannes Schindelin <johannes.schindelin@gmx.de>]

Kevin David reported a problem last October where a simple git fetch
would produce this error output:

	fatal: mmap failed: No error
	fatal: write error: Invalid argument

The reason was that several bits of our mmap() emulation left room for
improvement. These patches fix it, and made it already into Git
for Windows v2.6.2 and have been working without problems ever since.


Johannes Schindelin (3):
  win32mmap: set errno appropriately
  mmap(win32): avoid copy-on-write when it is unnecessary
  mmap(win32): avoid expensive fstat() call
