Re: [PATCH 3/3] read-cache: don't write index twice if we can't write shared index

[SZEDER Gábor <szeder.dev@xxxxxxxxx>]

This series, queued as 'nd/shared-index-fix', makes the 32 bit Linux
build job fail on Travis CI.  Unfortunately, all it can tell us about
the failure is this:

  Test Summary Report
  -------------------
  t1700-split-index.sh                             (Wstat: 256 Tests: 23
  Failed: 1)
    Failed test:  23
    Non-zero exit status: 1
  Files=809, Tests=18491, 401 wallclock secs ( 7.22 usr  1.60 sys + 263.16
  cusr 49.58 csys = 321.56 CPU)
  Result: FAIL

because it can't access the test's verbose log due to lack of
permissions.
