cciss: fix sysfs broken symlink regression

2008-11-13T17:55:56+00:00

commit 404443081ce5e6f68b5f7eda16c959835ff200c0 upstream

Regression introduced by commit 6ae5ce8e8d4de666f31286808d2285aa6a50fa40
("cciss: remove redundant code").

This patch fixes a broken symlink in sysfs that was introduced by the
above commit.  We broke it in 2.6.27-rc on or about 20080804.  Some
installers are broken if this symlink does not exist and they may not
detect the logical drives configured on the controller.  It does not
require being backported into 2.6.26.x or earlier kernels.

cciss: fix regression firmware not displayed in procfs

2008-11-13T17:55:56+00:00

commit 22bece00dc1f28dd3374c55e464c9f02eb642876 upstream

This regression was introduced by commit
6ae5ce8e8d4de666f31286808d2285aa6a50fa40 ("cciss: remove redundant code").

This patch fixes a regression where the controller firmware version is not
displayed in procfs.  The previous patch would be called anytime something
changed.  This will get called only once for each controller.

Revert "pktcdvd: push BKL down into driver"

2008-08-27T20:42:00+00:00

This reverts commit 5b6155ee70e9c4d2ad7e6f514c8eee06e2711c3a, because
the block device ioctl's really aren't ready for it.

In particular, the "struct file *" and the "struct inode *" arguments do
not necessarily match, which means that the unlocked version of the
ioctl (that only gets a "struct file *") isn't actually able to handle
the cases it needs to handle.

This fixes bugzilla

brd: fix name argument of unregister_blkdev()

2008-08-20T22:40:30+00:00

The name of brd block device is "ramdisk", it's not "brd".
(The block device is registered by register_blkdev(RAMDISK_MAJOR, "ramdisk")
So it should be unregistered by unregister_blkdev(RAMDISK_MAJOR, "ramdisk")

nbd: fix memory leak of nbd_dev array

2008-08-20T22:40:30+00:00

We leak the memory allocated for the nbd_dev array at multiple places.
Fix them by either adding a kfree() or by rearranging code to return
before we allocate the memory.
