LinuxLists.cc - [PATCH v5 00/19] Replace PCI pool by DMA pool API

2017-03-08 16:29:32

Subject: [PATCH v5 00/19] Replace PCI pool by DMA pool API

The current PCI pool API are simple macro functions direct expanded to
the appropriate dma pool functions. The prototypes are almost the same
and semantically, they are very similar. I propose to use the DMA pool
API directly and get rid of the old API.

This set of patches, replaces the old API by the dma pool API
and remove the defines.

Changes in v5:
- Re-worded the cover letter (remove sentence about checkpatch.pl)
- Rebased series onto next-20170308
- Fix typos in commit message
- Added Acked-by Tags

Changes in v4:
- Rebased series onto next-20170301
- Removed patch 20/20: checks done by checkpath.pl, no longer required.
Thanks to Peter and Joe for their feedbacks.
- Added Reviewed-by tags

Changes in v3:
- Rebased series onto next-20170224
- Fix checkpath.pl reports for patch 11/20 and patch 12/20
- Remove prefix RFC
Changes in v2:
- Introduced patch 18/20
- Fixed cosmetic changes: spaces before brace, live over 80 characters
- Removed some of the check for NULL pointers before calling dma_pool_destroy
- Improved the regexp in checkpatch for pci_pool, thanks to Joe Perches
- Added Tested-by and Acked-by tags

This replaces remaining occurences of pci_pool by dma_pool, as
this is the new API that could be used for that purpose.

[permalink] [raw]

Subject: [PATCH v5 09/19] scsi: csiostor: Replace PCI pool old API

The PCI pool API is deprecated. This commit replaces the PCI pool old
API by the appropriate function with the DMA pool API. It also updates
the name of some variables and the content of comments, accordingly.

My only concern is:
- what hardware did this get tested with? Since this affects all e100
parts, it would be hard to believe that all the affected hardware was
used in testing.

This was tested by compilation only(See
https://lkml.org/lkml/2017/2/8/661). However this series removes macro
definitions of the old pci_pool interface and replace call sites by what
the macra was calling.

Here are the macros that this series removes from include/pci.h:

#define pci_pool dma_pool
#define pci_pool_create(name, pdev, size, align, allocation) \
dma_pool_create(name, &pdev->dev, size, align, allocation)
#define pci_pool_destroy(pool) dma_pool_destroy(pool)
#define pci_pool_alloc(pool, flags, handle) dma_pool_alloc(pool, flags, handle)
#define pci_pool_zalloc(pool, flags, handle) \
dma_pool_zalloc(pool, flags, handle)
#define pci_pool_free(pool, vaddr, addr) dma_pool_free(pool, vaddr, add

So this should not affect run time.

We cannot test a patch like this one on all affected platforms/drivers
(at runtime). Simply because we have not the hw. As Peter said, we
tested this by compilation only for now via make allyesconfig. That's up
to the maintainer of the subsystem to test and ack this, imho.
I agree with Peter, this should not affect runtime (as semantically it's
compatible and have been validated statically and semantically by your
compiler)

Romain

drivers/block/DAC960.c:441:3-19: WARNING: NULL check before freeing functions like kfree, debugfs_remove, debugfs_remove_recursive or usb_free_urb is not needed. Maybe consider reorganizing relevant code to avoid passing NULL values.

NULL check before some freeing functions is not needed.

Based on checkpatch warning
"kfree(NULL) is safe this check is probably not required"
and kfreeaddr.cocci by Julia Lawall.
