[PATCH v3 2/2] xfstests btrfs/316: test send / receive

Jan Schmidt
2013-08-08T08:17:29Z

Basic send / receive functionality test for btrfs. Requires current
version of fsstress built (-x support). Relies on fssum tool but can
skip the test if it failed to build.

+# FSQA Test No. 316
+#
+# Run fsstress to create a reasonably strange file system, make a
+# snapshot (base) and run more fsstress. Then take another snapshot
+# (incr) and send both snapshots to a temp file. Remake the file
+# system and receive from the files. Check both states with fssum.
