[CRIU] [PATCH 0/3] zdtm: take care of short reads

[Mike Rapoport]

Hi,

On loaded systems read may return less data then requested and it's
perfectly Ok. However, some zdtm tests expect that large chunks of data
will be read in one go and fail when short reads happen.

These patches try to fix it by using {read,write}_data helpers that do not
treat incomplete IO operations as error.

I've updated some of the tests to use these new helpers, but I might have
miss something.

The last patch is not strictly related, it's just when I was looking for
read() calls I've found out that several socket tests duplicate some code. 

Mike Rapoport (3):
  zdtm: lib: add {read,write}_data helpers
  zdtm: use {read,write}_data where applicable
  zdtm: move common code to the library
