Replace OBD_CPT_ALLOC, OBD_CPT_ALLOC_PTR, and OBD_CPT_ALLOC_GFP by corresponding calls to kzalloc_node. The semantic patch for the OBD_CPT_ALLOC case is as follows: (http://coccinelle.lip6.fr/). // <smpl> @@ expression ptr,cptab,cpt,size; @@ - OBD_CPT_ALLOC(ptr, cptab, cpt, size) + ptr = kzalloc_node(size, GFP_NOFS, cfs_cpt_spread_node(cptab, cpt)) // </smpl> Note that the original OBD macros would check if the cptab argument was NULL and fall back on kzalloc in that case. Oleg Drokin argues that this test is not needed because the code containing these calls is only invoked after initialization has been completed, in which case the possible cptab arguments are not NULL.

Kfree can cope with a null argument, so drop null tests.

Likewise, in the first two failure cases of ptlrpc_lprocfs_nrs_seq_write, no cleanup is needed, so just drop the goto and return directly.

Kfree can cope with a null argument, so drop null tests. The semantic patch that identifies this issue is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression ptr; @@ - if (ptr != NULL) kfree(ptr); // </smpl> The first part of the patch introduces new labels to avoid unnecessary calls to kfree. In addition, lprof->lp_md is always null in the cleanup code at the end of the function, so that kfree is just dropped.

Kfree can cope with a null argument, so drop null tests. The semantic patch that finds this issue is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression ptr; @@ - if (ptr != NULL) kfree(ptr); // </smpl> In the first case, llss can never be null at the point of the kfree anyway. In the second set of changes, the gotos are either eliminated, when no freeing is needed (hss failure case), or rewritten so that there is no call to free on data that has not yet been allocated (free_hss goto case). There is no goto at which attr is not null, so the out label is simply dropped. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

The `COMEDI_SRF_...` macros define flag combinations in the `runflags` member of `struct comedi_subdevice`. They are only used directly in "comedi_fops.c", so move them to there.

Ian Abbott authored
The `COMEDI_SRF_FREE_SPRIV` flag in the `runflags` member of `struct comedi_subdevice` indicates that the memory pointed to by the `private` member can be automatically freed by the comedi core on subdevice clean-up (when the low-level comedi device is being "detached"). the flag doesn't really belong in `runflags`, but it was somewhere convenient to keep it without having to add a new member to the structure. Rather than access the `COMEDI_SRF_FREE_SPRIV` flag directly, use some new wrapper functions: * comedi_can_auto_free_spriv(s) - checks whether the subdevice's `s->private` points to memory that can be freed automatically. * comedi_set_spriv_auto_free(s) - marks the subdevice as having a `s->private` that points to memory that can be freed automatically. Export `comedi_set_spriv_auto_free()` for use by the low-level comedi driver modules, in particular the "amplc_dio200_common" module.
