[PATCH 8/20] staging: lustre: llite: statahead: remove unneeded null test before free

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

 



Kfree can cope with a null argument, so drop null tests.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@ expression ptr; @@

- if (ptr != NULL)
  kfree(ptr);
// </smpl>
