Subject: [PATCH v3 0/4] PCI: Clean up pci-sysfs.c
Date: Thu, 15 Aug 2019 09:33:49 -0600 [thread overview]
Message-ID: <20190815153352.86143-1-skunberg.kelsey@gmail.com> (raw)
In-Reply-To: <20190813204513.4790-1-skunberg.kelsey@gmail.com>
This series is designed to clean up device attributes and permissions in
pci-sysfs.c. Then move the sysfs SR-IOV functions from pci-sysfs.c to
iov.c for better organization.
Patch 1: Define device attributes with DEVICE_ATTR* instead of __ATTR*.
Patch 2: Change permissions from symbolic to the preferred octal.
Patch 3: Change DEVICE_ATTR() with 0220 permissions to DEVICE_ATTR_WO().
Patch 4: Move sysfs SR-IOV functions to iov.c to keep the feature's code
together.
Patch 1, 2, and 4 will report unusual permissions '0664' used from the
following:
static DEVICE_ATTR(sriov_numvfs, 0664, sriov_numvfs_show,
sriov_numvfs_store);
static DEVICE_ATTR(sriov_drivers_autoprobe, 0664,
sriov_drivers_autoprobe_show,
sriov_drivers_autoprobe_store);
This series preserves the existing permissions set in:
commit 0e7df22401a3 ("PCI: Add sysfs sriov_drivers_autoprobe to control
VF driver binding")
commit 1789382a72a5 ("PCI: SRIOV control and status via sysfs")
Either adding a comment verifying permissions are okay or changing the
permissions is to be completed with a new patch.
Changes since v1:
Add patch 1 and 2 to fix the way device attributes are defined
and change permissions from symbolic to octal. Patch 4 which moves
sysfs SR-IOV functions to iov.c will then apply cleaner.
Changes since v2:
Patch 1: Commit log updated. Example shows DEVICE_ATTR_RO()
example instead of DEVICE_ATTR(). DEVICE_ATTR() should be avoided
unless the files have unusual permissions. Changed to reflect a
more encouraged usage. Also updated regex to be accurate.
Patch 3: [NEW] Add patch to change DEVICE_ATTR() with 0220
permissions to DEVICE_ATTR_WO().
Updated series log to reflect new patch and unusual permissions
information.
