+Subject: [PATCH 1/4] DDF: Cleanup validate_geometry_ddf_container()
+
+Move the function up so that the function declaration is not necessary
+and remove the unused arguments to the function.
+
+No functional changes are intended but will help with a bug fix in the
+next patch.

+Subject: [PATCH 2/4] DDF: Fix NULL pointer dereference in
+ validate_geometry_ddf()
+
+A relatively recent patch added a call to validate_geometry() in
+Manage_add() that has level=LEVEL_CONTAINER and chunk=NULL.
+
+This causes some ddf tests to segfault which aborts the test suite.
+
+To fix this, avoid dereferencing chunk when the level is
+LEVEL_CONTAINER or LEVEL_NONE.

+Fixes: 1f5d54a06df0 ("Manage: Call validate_geometry when adding drive to external container")

+Subject: [PATCH 3/4] mdadm/Grow: Fix use after close bug by closing after fork
+
+The test 07reshape-grow fails most of the time. But it succeeds around
+1 in 5 times. When it does succeed, it causes the tests to die because
+mdadm has segfaulted.
+
+The segfault was caused by mdadm attempting to repoen a file
+descriptor that was already closed. The backtrace of the segfault
+was:
+

+
+The file descriptor was closed early in Grow_continue(). The noted commit
+moved the close() call to close the fd above the fork which caused the
+parent process to return with a closed fd.
+
+This meant reshape_array() and Grow_continue() would return in the parent
+with the fd forked. The fd would eventually be passed to reopen_mddev()
+which returned an unhandled NULL from fd2devnm() which would then be
+dereferenced in devnm2devid.
+
+Fix this by moving the close() call below the fork. This appears to
+fix the 07revert-grow test. While we're at it, switch to using
+close_fd() to invalidate the file descriptor.

+
+Not all struct superswitch implement a get_bad_blocks() function,
+yet mdmon seems to call it without checking for NULL and thus
+occasionally segfaults in the test 10ddf-geometry.
+
+Fix this by checking for NULL before calling it.
