LGTM.

With this patch, I could merge the following patches:
[PATCH 2.22 02/14] CVE-2017-15670: glob: Fix one-byte overflow [BZ #22320]
[PATCH 2.22 03/14] glob: Add new test tst-glob-tilde
[PATCH 2.22 05/14] glob: Fix buffer overflow during GLOB_TILDE unescaping [BZ #22332]

If there are any objections, I plan to merge it next Tuesday.

After merging these patches, the following patch would still be pending from
your initial submission:
[PATCH 2.22 11/14] linux: make getcwd(3) fail if it cannot obtain an absolute path [BZ #22679]

Thanks!
