[PATCH] fix cgroup-inflicted breakage in block_dev.c

2008-06-23T12:30:55Z

devcgroup_inode_permission() expects MAY_FOO, not FMODE_FOO; kindly keep your misdesign consistent if you positively have to inflict it on the kernel. Signed-off-by: Al Viro

devscgroup: check for device permissions at mount time

2008-06-06T18:29:11Z

Currently even if a task sits in an all-denied cgroup it can still mount any block device in any mode it wants. Put a proper check in do_open for block device to prevent this.

fs/block_dev.c: remove #if 0'ed code

2008-02-19T09:04:00Z

Commit b2e895dbd80c420bfc0937c3729b4afe073b3848 #if 0'ed this code stating: <-- snip --> [PATCH] revert blockdev direct io back to 2.6.19 version Andrew Vasquez is reporting as-iosched oopses and a 65% throughput slowdown due to the recent special-casing of direct-io against blockdevs. We don't know why either of these things are occurring. The patch minimally reverts us back to the 2.6.19 code for a 2.6.20 release. <-- snip --> It has since been dead code, and unless someone wants to revive it now it's time to remove it. This patch also makes bio_release_pages() static again and removes the ki_bio_count member from struct kiocb, reverting changes that had been done for this dead code.

Introduce path_put()

Embed a struct path into struct nameidata instead of nd->{dentry,mnt}

2008-02-15T05:13:33Z

This is the central patch of a cleanup series. In most cases there is no good reason why someone would want to use a dentry for itself. This series reflects that fact and embeds a struct path into nameidata. Together with the other patches of this series - it enforced the correct order of getting/releasing the reference count on pairs - it prepares the VFS for stacking support since it is essential to have a struct path in every place where the stack can be traversed - it reduces the overall code size: without patch series: text data bss dec hex filename 5321639 858418 715768 6895825 6938d1 vmlinux with patch series: text data bss dec hex filename 5320026 858418 715768 6894212 693284 vmlinux This patch: Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.

Driver core: convert block from raw kobjects to core devices

2008-01-25T04:40:36Z

This moves the block devices to /sys/class/block. It will create a flat list of all block devices, with the disks and partitions in one directory. For compatibility /sys/block is created and contains symlinks to the disks. /sys/class/block |-- sda -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda |-- sda1 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda1 |-- sda10 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda10 |-- sda5 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda5 |-- sda6 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda6 |-- sda7 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda7 |-- sda8 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda8 |-- sda9 -> ../../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda/sda9 `-- sr0 -> ../../devices/pci0000:00/0000:00:1f.2/host1/target1:0:0/1:0:0:0/block/sr0 /sys/block/ |-- sda -> ../devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0/block/sda `-- sr0 -> ../devices/pci0000:00/0000:00:1f.2/host1/target1:0:0/1:0:0:0/block/sr0 Signed-off-by: Kay Sievers Signed-off-by: Greg Kroah-Hartman

Slab API: remove useless ctor parameter and reorder parameters

2007-10-17T15:42:45Z

Slab constructors currently have a flags parameter that is never used. And the order of the arguments is opposite to other slab functions. The object pointer is placed before the kmem_cache pointer.
