The branch, v3-6-test has been updated
via 1f601d1 Ensure we test the dirsort module in make test.
via 8a1ec80 Remove unneeded initializations (we already talloc_zero).
via ffc2d25 Remove the use of dirfd inside the vfs_dirsort.c.
via 8a761c7 Convert mtime from a time_t to a struct timespec.
via 052f74c Check SMB_VFS_NEXT_OPENDIR return in dirsort_opendir().
via a2da5a7 Clean error paths in opendir and fd_opendir by only setting handle data on success.
via 582d8ca Protect open_and_sort_dir() from the directory changing size.
via f818221 Use an index i rather than re-using a state variable.
via f34063e Protect against early error in SMB_VFS_NEXT_READDIR.
via e2118fd Change source3/modules/vfs_dirsort.c from MALLOC -> TALLOC.
from 1e064e9 WHATSNEW: Start release notes for Samba 3.6.17.
