hfsplus-Add-an-ioctl-to-bless-files.patch
View File

@ -1,98 +0,0 @@
Making an hfsplus partition bootable requires the ability to "bless" a
file by putting its inode number in the volume header. Doing this from
userspace on a mounted filesystem is impractical since the kernel will
write back the original values on unmount. Add an ioctl to allow userspace
to update the volume header information based on the target file.
Signed-off-by: Matthew Garrett <mjg@redhat.com>

Kept the ioctl in the hfs code, but moved it to a different range to reduce
reduce the chances of someone stepping on it with another filesystem.

an array of 8 bit values, but TN1150 defines it as being an array of 32 bit

From dadfe1ad137e6fbe251b4a5dc310840cfe414db4 Mon Sep 17 00:00:00 2001
From: Josh Boyer <jwboyer@redhat.com>
Date: Mon, 20 Feb 2012 15:28:39 -0500
Subject: [PATCH] ums_realtek: do not use stack memory for DMA in
__do_config_autodelink
__do_config_autodelink passes the data variable to the transport function.
If the calling functions pass a stack variable, this will eventually trigger
a DMA-API debug backtrace for mapping stack memory in the DMA buffer. Fix
this by calling kmemdup for the passed data instead.
