[PATCHv2 0/3] Introduce simple_open()

[Stephen Boyd]

I noticed that if I want to tweak debugfs file ops I need to copy
the implementation of default_open() in fs/debugfs/file.c. I went
to look for an exported function that would be common across all
debugfs users but I couldn't find any.

This patchset moves default_open() to libfs so that other filesystems
can use it (although almost 99% of users are debugfs clients). Andrew
has picked up the first patch but I'm including it here for
completeness.

This is based on linux-next at next-20120302

Changes since v1:
 * Fixed coccinelle script
 * Included mega patch to move all current users
