[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The patch titled
     Subject: radix tree test suite: record order in each item
has been removed from the -mm tree.  Its filename was
     radix-tree-test-suite-record-order-in-each-item.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Matthew Wilcox <mawilcox@xxxxxxxxxxxxx>
Subject: radix tree test suite: record order in each item

This probably doubles the size of each item allocated by the test suite
but it lets us check a few more things, and may be needed for upcoming API
changes that require the caller pass in the order of the entry.
