From: Julia Lawall <julia.law...@lip6.fr> 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/) // <smpl> @@ expression ptr,size; @@ - OBD_ALLOC(ptr,size) + ptr = kzalloc(size, GFP_NOFS) @@ expression ptr, size; @@ - OBD_FREE(ptr, size); + kfree(ptr); // </smpl> Signed-off-by: Julia Lawall <julia.law...@lip6.fr> --- drivers/staging/lustre/lustre/lmv/lmv_intent.c | 4 +-- drivers/staging/lustre/lustre/lmv/lmv_obd.c | 28 ++++++++++++------------- 2 files changed, 16 insertions(+), 16 deletions(-) diff -u -p a/drivers/staging/lustre/lustre/lmv/lmv_obd.c b/drivers/staging/lustre/lustre/lmv/lmv_obd.c --- a/drivers/staging/lustre/lustre/lmv/lmv_obd.c +++ b/drivers/staging/lustre/lustre/lmv/lmv_obd.c @@ -442,7 +442,7 @@ static void lmv_del_target(struct lmv_ob if (lmv->tgts[index] == NULL) return; - OBD_FREE_PTR(lmv->tgts[index]); + kfree(lmv->tgts[index]); lmv->tgts[index] = NULL; return; } @@ -488,7 +488,7 @@ static int lmv_add_target(struct obd_dev while (newsize < index + 1) newsize <<= 1; - OBD_ALLOC(newtgts, sizeof(*newtgts) * newsize); + newtgts = kcalloc(newsize, sizeof(*newtgts), GFP_NOFS); if (newtgts == NULL) { lmv_init_unlock(lmv); return -ENOMEM; @@ -505,13 +505,13 @@ static int lmv_add_target(struct obd_dev lmv->tgts_size = newsize; smp_rmb(); if (old) - OBD_FREE(old, sizeof(*old) * oldsize); + kfree(old); CDEBUG(D_CONFIG, "tgts: %p size: %d\n", lmv->tgts, lmv->tgts_size); } - OBD_ALLOC_PTR(tgt); + tgt = kzalloc(sizeof(*tgt), GFP_NOFS); if (!tgt) { lmv_init_unlock(lmv); return -ENOMEM; @@ -750,7 +750,7 @@ repeat_fid2path: /* sigh, has to go to another MDT to do path building further */ if (remote_gf == NULL) { remote_gf_size = sizeof(*remote_gf) + PATH_MAX; - OBD_ALLOC(remote_gf, remote_gf_size); + remote_gf = kzalloc(remote_gf_size, GFP_NOFS); if (remote_gf == NULL) { rc = -ENOMEM; goto out_fid2path; @@ -781,7 +781,7 @@ repeat_fid2path: out_fid2path: if (remote_gf != NULL) - OBD_FREE(remote_gf, remote_gf_size); + kfree(remote_gf); return rc; } @@ -984,7 +984,7 @@ static int lmv_iocontrol(unsigned int cm return -EAGAIN; LASSERT(tgt && tgt->ltd_exp); - OBD_ALLOC_PTR(oqctl); + oqctl = kzalloc(sizeof(*oqctl), GFP_NOFS); if (!oqctl) return -ENOMEM; @@ -995,7 +995,7 @@ static int lmv_iocontrol(unsigned int cm qctl->qc_valid = QC_MDTIDX; qctl->obd_uuid = tgt->ltd_uuid; } - OBD_FREE_PTR(oqctl); + kfree(oqctl); break; } case OBD_IOC_CHANGELOG_SEND: @@ -1327,7 +1327,7 @@ static int lmv_setup(struct obd_device * return -EINVAL; } - OBD_ALLOC(lmv->tgts, sizeof(*lmv->tgts) * 32); + lmv->tgts = kcalloc(32, sizeof(*lmv->tgts), GFP_NOFS); if (lmv->tgts == NULL) return -ENOMEM; lmv->tgts_size = 32; @@ -1380,7 +1380,7 @@ static int lmv_cleanup(struct obd_device continue; lmv_del_target(lmv, i); } - OBD_FREE(lmv->tgts, sizeof(*lmv->tgts) * lmv->tgts_size); + kfree(lmv->tgts); lmv->tgts_size = 0; } return 0; @@ -1437,7 +1437,7 @@ static int lmv_statfs(const struct lu_en if (rc) return rc; - OBD_ALLOC(temp, sizeof(*temp)); + temp = kzalloc(sizeof(*temp), GFP_NOFS); if (temp == NULL) return -ENOMEM; @@ -1473,7 +1473,7 @@ static int lmv_statfs(const struct lu_en } out_free_temp: - OBD_FREE(temp, sizeof(*temp)); + kfree(temp); return rc; } @@ -1769,7 +1769,7 @@ lmv_enqueue_remote(struct obd_export *ex goto out; } - OBD_ALLOC_PTR(rdata); + rdata = kzalloc(sizeof(*rdata), GFP_NOFS); if (rdata == NULL) { rc = -ENOMEM; goto out; @@ -1780,7 +1780,7 @@ lmv_enqueue_remote(struct obd_export *ex rc = md_enqueue(tgt->ltd_exp, einfo, it, rdata, lockh, lmm, lmmsize, NULL, extra_lock_flags); - OBD_FREE_PTR(rdata); + kfree(rdata); out: ldlm_lock_decref(&plock, pmode); return rc; diff -u -p a/drivers/staging/lustre/lustre/lmv/lmv_intent.c b/drivers/staging/lustre/lustre/lmv/lmv_intent.c --- a/drivers/staging/lustre/lustre/lmv/lmv_intent.c +++ b/drivers/staging/lustre/lustre/lmv/lmv_intent.c @@ -99,7 +99,7 @@ static int lmv_intent_remote(struct obd_ goto out; } - OBD_ALLOC_PTR(op_data); + op_data = kzalloc(sizeof(*op_data), GFP_NOFS); if (op_data == NULL) { rc = -ENOMEM; goto out; @@ -142,7 +142,7 @@ static int lmv_intent_remote(struct obd_ it->d.lustre.it_lock_mode = pmode; out_free_op_data: - OBD_FREE_PTR(op_data); + kfree(op_data); out: if (rc && pmode) ldlm_lock_decref(&plock, pmode); _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
