+# FS QA Test No. 759
+#
+# This is a regression test for commit 2a6ca4baed62 ("xfs: make sure the rt
+# allocator doesn't run off the end") which fixes an overflow error in the
+# _near realtime allocator.  If the rt bitmap ends exactly at the end of a
+# block and the number of rt extents is large enough to allow an allocation
+# request larger than the maximum extent size, it's possible that during a
+# large allocation request, the allocator will fail to constrain maxlen on the
+# second run through the loop, and the rt bitmap range check will run right off
+# the end of the rtbitmap file.  When this happens, xfs triggers a verifier
+# error and returns EFSCORRUPTED.
