Eugene Syromyatnikov
evgsyr at gmail.com
Wed Sep 21 03:12:37 UTC 2016
* configure.ac (AC_CHECK_HEADERS): Add linux/dqblk_xfs.h, sys/quota.h.
* tests/.gitignore: Add quotactl, quotactl-xfs
* tests/Makefile.am (check_PROGRAMS): Likewise.
(DECODER_TESTS): Add quotactl.test, quotactl-v.test,
quotactl-xfs.test, quotactl-xfs-v.test.
(EXTRA_DIST): quotactl.h
* quotactl-v.test: New file.
* quotactl-xfs-v.test: Likewise.
* quotactl-xfs.c: Likewise.
* quotactl-xfs.test: Likewise.
* quotactl.c: Likewise.
* quotactl.h: Likewise.
* quotactl.test: Likewise.
