[PATCH 0/2] Introduce simple_open()

[Stephen Boyd <sboyd@codeaurora.org>]

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). I
wrote a semantic patch to find all the kernel users and ended up
with a nice diff:

 58 files changed, 150 insertions(+), 560 deletions(-)

I will send those patches as a follow up to these two once we settle
on naming and merging strategies for the patches.

  libfs: Add simple_open()
