[PATCH 3/5] sfdisk: do not depend on arch for packed attribute

[PATCH 3/5] sfdisk: do not depend on arch for packed attribute

[Davidlohr Bueso]

From: Davidlohr Bueso <dave@gnu.org>

The packed gcc function attribute is moved to c.h and the arch-specific checks are removed
since there is no harm in other platforms having the attribute, it will just make no difference.

Why not merge this commit with the previous one? They are for the same
logical change, and otherwise it termporarily introduces a warning.

[PATCH 1/2] blkdev: add is_blkdev function

[Davidlohr Bueso]

From: Davidlohr Bueso <dave@gnu.org>

We should have the most basic of checks in this library to see whether or not a block device is being used.

  I have removed the PACKED macro at all and used __attribute__
  keyword in the code.
