[PATCH v3 0/3] die_errno()

[Thomas Rast <trast@student.ethz.ch>]

First off, thanks for the extensive review and discussion...

[1/3] I changed the snprintf handling to tack the error onto the
  format and pass that to die_routine().  I still think it's crazy to
  invent new format characters, but who knows.

[2/3] Fixed as per Johannes Sixt's comments.

[3/3] Removed the terrible empty-lines mess caused by pilot error.

  Removed...  I'm not enough of an expert to say if
  commit_index_files() can only fail because the disk is full, so I
  figured it would still be an improvement to show the real error.

  If you just meant that it should go in a separate patch because it's
  not a die->die_errno change, I can do that, it just feels like
  overkill because it is morally the same change, but in a case where
  I cannot apply the die_errno shortcut.


Thomas Rast (3):
  Introduce die_errno() that appends strerror(errno) to die()
  Convert existing die(..., strerror(errno)) to die_errno()
  Use die_errno() instead of die() when checking syscalls
