  "message": "radix tree test suite: add item_delete_rcu()\n\nCurrently the lifetime of \"struct item\" entries in the radix tree are\nnot controlled by RCU, but are instead deleted inline as they are\nremoved from the tree.\n\nIn the following patches we add a test which has threads iterating over\nitems pulled from the tree and verifying them in an\nrcu_read_lock()/rcu_read_unlock() section.  This means that though an\nitem has been removed from the tree it could still be being worked on by\nother threads until the RCU grace period expires.  So, we need to\nactually free the \"struct item\" structures at the end of the grace\nperiod, just as we do with \"struct radix_tree_node\" items.\n\nLink: http://lkml.kernel.org/r/20180503192430.7582-4-ross.zwisler@linux.intel.com\nSigned-off-by: Ross Zwisler \u003cross.zwisler@linux.intel.com\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: CR, Sapthagirish \u003csapthagirish.cr@intel.com\u003e\nCc: Dan Williams \u003cdan.j.williams@intel.com\u003e\nCc: Dave Chinner \u003cdavid@fromorbit.com\u003e\nCc: Jan Kara \u003cjack@suse.cz\u003e\nCc: Matthew Wilcox \u003cwilly@infradead.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
