[PATCH 0/5] losetup: rewrite

[PATCH 0/5] losetup: rewrite

[Davidlohr Bueso]

This is the first in a number of patchset series to come to rewrite this
tool using the loopdev library. We also aim to add it to the sys-utils/
directory in the attempt to start cleaning up mount/.

Instead of a complete rewrite from scratch, like it was initially
planned, its better to do it incrementally, which makes it easier to
regression test.

Thanks,
Davidlohr

 I agree, do it incrementally is better for review. Anyway for merge
 into master branch we need all changes.

 Suggestion:

  1. use directly lib/loopdev.c stuff in mount.c and umount.c 

     -- I did this yesterday. So you don't have to fight with 
        unreadable spaghetti in mount.c (check_loop() is hell)...


  2. remove obsolete things (e.g. #ifdef !MAIN)

  3. remove code around old non-64bit ioctls

  4. remove lomount.h and loop.h (include/loopdev.h has to be enough)

  5. move mount/lomount.c to sys-utils/losetup.c

  6. use lib/loopdev.c stuff in sys-utils/losetup.c

     - it should be possible to initialize one struct loopdev_cxt in main() and
       use it in all operations

     - rather than many variables (capacity, find, all, showdev,
       assoc, delete, ...) use any enum for requested operation and
       switch(command) as a core of the main().
