lustre: obdclass: linux: Replace uses of OBD_{ALLOC, FREE}_LARGE
Author: Julia Lawall <Julia.Lawall@lip6.fr>
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/)
//
@@
expression ptr,size;
@@
- OBD_ALLOC_LARGE(ptr,size)
+ ptr = libcfs_kvzalloc(size, GFP_NOFS)
@@
expression ptr,size;
@@
- OBD_FREE_LARGE(ptr, size);
+ kvfree(ptr);
//
