Subject: [PATCH v3 0/3] lib/string_helpers et al.: Change return value of strreplace()

It's more convenient to have strreplace() to return the pointer to
 the string itself. This will help users to make their code better.

The patch 1 kills the only user of the returned value of strreplace(),
Patch 2 converts the return value of strreplace(). And patch 3 shows
how it may be useful. That said, the series can be routed via fs tree,
with or without the last patch.

In v3:
- rebased on top of latest Linux Next

In v2:
- removed not anymore used variable (LKP)
- added tag (Jan)
- fixed wording (Kees)
- actually return the pointer to the string itself

Andy Shevchenko (3):
  jbd2: Avoid printing outside the boundary of the buffer
  lib/string_helpers: Change returned value of the strreplace()
  kobject: Use return value of strreplace()
