Subject: drivers/md: introduce missing kfree
From: Julia Lawall <julia@diku.dk>

Error handling code following a kmalloc should free the allocated data.

The semantic match that finds the problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@r exists@
local idexpression x;
statement S;
expression E;
identifier f,f1,l;
position p1,p2;
expression *ptr != NULL;

)

print "* file: %s kmalloc %s return %s" % (p1[0].file,p1[0].line,p2[0].line)
