* kernel.h: remove ancient __FUNCTION__ hackRasmus Villemoes2017-09-231-1/+1
| | | | | | | | | | | | | | | | __FUNCTION__ hasn't been treated as a string literal since gcc 3.4, so this only helps people who only test-compile using 3.3 (compiler-gcc3.h barks at anything older than that). Besides, there are almost no occurrences of __FUNCTION__ left in the tree.

* xen-blkfront: check for null drvdata in blkback_changed (XenbusStateClosing)Cathy Avery2016-08-261-1/+2
| | | | | | | | | | | | | | | commit a54c8f0f2d7df525ff997e2afe71866a1a013064 upstream. xen-blkfront will crash if the check to talk_to_blkback() in blkback_changed()(XenbusStateInitWait) returns an error. The driver data is freed and info is set to NULL. Later during the close process via talk_to_blkback's call to xenbus_dev_fatal() the null pointer is passed to and dereference in blkfront_closing.
