[PATCH 5/7] lustre: obdclass: Replace uses of OBD_{ALLOC,FREE}_LARGE

From: Julia Lawall
Date: Thu Jun 11 2015 - 08:12:44 EST


Replace uses of OBD_ALLOC_LARGE by libcfs_kvzalloc and OBD_FREE_LARGE by
kvfree.

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

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

- OBD_ALLOC_LARGE(ptr,size)
+ ptr = libcfs_kvzalloc(size, GFP_NOFS)

@@
expression ptr,size;
@@

- OBD_FREE_LARGE(ptr, size);
+ kvfree(ptr);
// </smpl>
