[HPDD-discuss] [PATCH 5/7] lustre: obdclass: 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/lu_object.c | 8 ++++---- drivers/staging/lustre/lustre/obdclass/lustre_handles.c | 5 +++-- 2 files changed, 7 insertions(+), 6 deletions(-) diff --git a/drivers/staging/lustre/lustre/obdclass/lustre_handles.c b/drivers/staging/lustre/lustre/obdclass/lustre_handles.c index 1cfaabf..35a94a8 100644 --- a/drivers/staging/lustre/lustre/obdclass/lustre_handles.c +++ b/drivers/staging/lustre/lustre/obdclass/lustre_handles.c @@ -198,7 +198,8 @@ int class_handle_init(void) LASSERT(handle_hash == NULL); - OBD_ALLOC_LARGE(handle_hash, sizeof(*bucket) * HANDLE_HASH_SIZE); + handle_hash = libcfs_kvzalloc(sizeof(*bucket) * HANDLE_HASH_SIZE, + GFP_NOFS); if (handle_hash == NULL) return -ENOMEM; @@ -249,7 +250,7 @@ void class_handle_cleanup(void) count = cleanup_all_handles(); - OBD_FREE_LARGE(handle_hash, sizeof(*handle_hash) * HANDLE_HASH_SIZE); + kvfree(handle_hash); handle_hash = NULL; if (count != 0) diff --git a/drivers/staging/lustre/lustre/obdclass/lu_object.c b/drivers/staging/lustre/lustre/obdclass/lu_object.c index eae6606..4d9b633 100644 --- a/drivers/staging/lustre/lustre/obdclass/lu_object.c +++ b/drivers/staging/lustre/lustre/obdclass/lu_object.c @@ -2121,7 +2121,7 @@ void lu_buf_free(struct lu_buf *buf) LASSERT(buf); if (buf->lb_buf) { LASSERT(buf->lb_len > 0); - OBD_FREE_LARGE(buf->lb_buf, buf->lb_len); + kvfree(buf->lb_buf); buf->lb_buf = NULL; buf->lb_len = 0; } @@ -2133,7 +2133,7 @@ void lu_buf_alloc(struct lu_buf *buf, int size) LASSERT(buf); LASSERT(buf->lb_buf == NULL); LASSERT(buf->lb_len == 0); - OBD_ALLOC_LARGE(buf->lb_buf, size); + buf->lb_buf = libcfs_kvzalloc(size, GFP_NOFS); if (likely(buf->lb_buf)) buf->lb_len = size; } @@ -2171,14 +2171,14 @@ int lu_buf_check_and_grow(struct lu_buf *buf, int len) if (len <= buf->lb_len) return 0; - OBD_ALLOC_LARGE(ptr, len); + ptr = libcfs_kvzalloc(len, GFP_NOFS); if (ptr == NULL) return -ENOMEM; /* Free the old buf */ if (buf->lb_buf != NULL) { memcpy(ptr, buf->lb_buf, buf->lb_len); - OBD_FREE_LARGE(buf->lb_buf, buf->lb_len); + kvfree(buf->lb_buf); } buf->lb_buf = ptr;
