[HPDD-discuss] [PATCH 6/7] lustre: obdclass: linux: Replace uses of OBD_{ALLOC, FREE}_LARGE

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> Signed-off-by: Julia Lawall <Julia.Lawall(a)lip6.fr&gt; --- drivers/staging/lustre/lustre/obdclass/linux/linux-module.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/staging/lustre/lustre/obdclass/linux/linux-module.c b/drivers/staging/lustre/lustre/obdclass/linux/linux-module.c index e3c6dcb..84f75dc 100644 --- a/drivers/staging/lustre/lustre/obdclass/linux/linux-module.c +++ b/drivers/staging/lustre/lustre/obdclass/linux/linux-module.c @@ -107,7 +107,7 @@ int obd_ioctl_getdata(char **buf, int *len, void *arg) * system, the high lock contention will hurt performance badly, * obdfilter-survey is an example, which relies on ioctl.
