From c5b895201c3097d8414ba520a06a545794400e0c Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Fri, 1 May 2015 17:51:14 +0200 Subject: [PATCH] staging: lustre: obdecho: Use kzalloc and kfree Replace OBD_ALLOC, OBD_ALLOC_WAIT, OBD_ALLOC_PTR, and OBD_ALLOC_PTR_WAIT by kalloc/kcalloc, and OBD_FREE and OBD_FREE_PTR by kfree. A simplified version of the semantic patch that makes these changes is as follows: (http://coccinelle.lip6.fr/) // @@ expression ptr,size; @@ - OBD_ALLOC(ptr,size) + ptr = kzalloc(size, GFP_NOFS) @@ expression ptr, size; @@ - OBD_FREE(ptr, size); + kfree(ptr); // Signed-off-by: Julia Lawall Signed-off-by: Greg Kroah-Hartman --- .../lustre/lustre/obdecho/echo_client.c | 42 +++++++++---------- 1 file changed, 21 insertions(+), 21 deletions(-) diff --git a/drivers/staging/lustre/lustre/obdecho/echo_client.c b/drivers/staging/lustre/lustre/obdecho/echo_client.c index d542e06d6cd3..cf645388dc75 100644 --- a/drivers/staging/lustre/lustre/obdecho/echo_client.c +++ b/drivers/staging/lustre/lustre/obdecho/echo_client.c @@ -479,13 +479,13 @@ static int echo_alloc_memmd(struct echo_device *ed, lsm_size = lov_stripe_md_size(1); LASSERT(*lsmp == NULL); - OBD_ALLOC(*lsmp, lsm_size); + *lsmp = kzalloc(lsm_size, GFP_NOFS); if (*lsmp == NULL) return -ENOMEM; - OBD_ALLOC((*lsmp)->lsm_oinfo[0], sizeof(struct lov_oinfo)); + (*lsmp)->lsm_oinfo[0] = kzalloc(sizeof(struct lov_oinfo), GFP_NOFS); if ((*lsmp)->lsm_oinfo[0] == NULL) { - OBD_FREE(*lsmp, lsm_size); + kfree(*lsmp); return -ENOMEM; } @@ -507,8 +507,8 @@ static int echo_free_memmd(struct echo_device *ed, struct lov_stripe_md **lsmp) lsm_size = lov_stripe_md_size(1); LASSERT(*lsmp != NULL); - OBD_FREE((*lsmp)->lsm_oinfo[0], sizeof(struct lov_oinfo)); - OBD_FREE(*lsmp, lsm_size); + kfree((*lsmp)->lsm_oinfo[0]); + kfree(*lsmp); *lsmp = NULL; return 0; } @@ -700,7 +700,7 @@ static struct lu_device *echo_device_alloc(const struct lu_env *env, int rc; int cleanup = 0; - OBD_ALLOC_PTR(ed); + ed = kzalloc(sizeof(*ed), GFP_NOFS); if (ed == NULL) { rc = -ENOMEM; goto out; @@ -798,7 +798,7 @@ out: case 2: cl_device_fini(&ed->ed_cl); case 1: - OBD_FREE_PTR(ed); + kfree(ed); case 0: default: break; @@ -895,7 +895,7 @@ static struct lu_device *echo_device_free(const struct lu_env *env, LASSERT(ed->ed_site == lu2cl_site(d->ld_site)); echo_site_fini(env, ed); cl_device_fini(&ed->ed_cl); - OBD_FREE_PTR(ed); + kfree(ed); return NULL; } @@ -1577,13 +1577,13 @@ static int echo_client_kbrw(struct echo_device *ed, int rw, struct obdo *oa, if (rw == OBD_BRW_WRITE) brw_flags = OBD_BRW_ASYNC; - OBD_ALLOC(pga, npages * sizeof(*pga)); + pga = kcalloc(npages, sizeof(*pga), GFP_NOFS); if (pga == NULL) return -ENOMEM; - OBD_ALLOC(pages, npages * sizeof(*pages)); + pages = kcalloc(npages, sizeof(*pages), GFP_NOFS); if (pages == NULL) { - OBD_FREE(pga, npages * sizeof(*pga)); + kfree(pga); return -ENOMEM; } @@ -1632,8 +1632,8 @@ static int echo_client_kbrw(struct echo_device *ed, int rw, struct obdo *oa, } OBD_PAGE_FREE(pgp->pg); } - OBD_FREE(pga, npages * sizeof(*pga)); - OBD_FREE(pages, npages * sizeof(*pages)); + kfree(pga); + kfree(pages); return rc; } @@ -1659,8 +1659,8 @@ static int echo_client_prep_commit(const struct lu_env *env, npages = batch >> PAGE_CACHE_SHIFT; tot_pages = count >> PAGE_CACHE_SHIFT; - OBD_ALLOC(lnb, npages * sizeof(struct niobuf_local)); - OBD_ALLOC(rnb, npages * sizeof(struct niobuf_remote)); + lnb = kcalloc(npages, sizeof(struct niobuf_local), GFP_NOFS); + rnb = kcalloc(npages, sizeof(struct niobuf_remote), GFP_NOFS); if (lnb == NULL || rnb == NULL) { ret = -ENOMEM; @@ -1738,9 +1738,9 @@ static int echo_client_prep_commit(const struct lu_env *env, out: if (lnb) - OBD_FREE(lnb, npages * sizeof(struct niobuf_local)); + kfree(lnb); if (rnb) - OBD_FREE(rnb, npages * sizeof(struct niobuf_remote)); + kfree(rnb); return ret; } @@ -1879,7 +1879,7 @@ echo_client_iocontrol(unsigned int cmd, struct obd_export *exp, int len, if (rc < 0) return rc; - OBD_ALLOC_PTR(env); + env = kzalloc(sizeof(*env), GFP_NOFS); if (env == NULL) return -ENOMEM; @@ -2010,7 +2010,7 @@ echo_client_iocontrol(unsigned int cmd, struct obd_export *exp, int len, out: lu_env_fini(env); - OBD_FREE_PTR(env); + kfree(env); /* XXX this should be in a helper also called by target_send_reply */ for (ack_lock = dummy_oti.oti_ack_locks, i = 0; i < 4; @@ -2050,7 +2050,7 @@ static int echo_client_setup(const struct lu_env *env, ec->ec_unique = 0; ec->ec_nstripes = 0; - OBD_ALLOC(ocd, sizeof(*ocd)); + ocd = kzalloc(sizeof(*ocd), GFP_NOFS); if (ocd == NULL) { CERROR("Can't alloc ocd connecting to %s\n", lustre_cfg_string(lcfg, 1)); @@ -2074,7 +2074,7 @@ static int echo_client_setup(const struct lu_env *env, spin_unlock(&tgt->obd_dev_lock); } - OBD_FREE(ocd, sizeof(*ocd)); + kfree(ocd); if (rc != 0) { CERROR("fail to connect to device %s\n", -- 2.20.1
