    Subject[PATCH 0/2] Introduce simple_open()
    Date
    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.
