REVISION SUMMARY
  file.cpp:947:60: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
  
    } else if (n > 0 && static_cast<size_t>(n) != bufferSize) {
  
  Tricky because the type of bufferSize depends on which #if branch was taken.

TEST PLAN
  Compiles without warning now (apparently I don't have statx available)

REPOSITORY
  R241 KIO

BRANCH
  master
