Revision 450ba0ea06b6ed3612d27f2b7127a9de4160f285 authored by Josef Bacik on 19 November 2010, 19:59:15 UTC, committed by Chris Mason on 27 November 2010, 18:37:51 UTC
There is a problem with how we use sget, it searches through the list of supers attached to the fs_type looking for a super with the same fs_devices as what we're trying to mount. This depends on sb->s_fs_info being filled, but we don't fill that in until we get to btrfs_fill_super, so we could hit supers on the fs_type super list that have a null s_fs_info. In order to fix that we need to go ahead and setup a blank root with a blank fs_info to hold fs_devices, that way our test will work out right and then we can set s_fs_info in btrfs_set_super, and then open_ctree will simply use our pre-allocated root and fs_info when setting everything up.

The "Communication CPU to Application CPU Interface" (CAIF) is a packet
based connection-oriented MUX protocol developed by ST-Ericsson for use
with its modems. It is accessed from user space as sockets (PF_CAIF).
Say Y (or M) here if you build for a phone product (e.g. Android or
MeeGo ) that uses CAIF as transport, if unsure say N.
If you select to build it as module then CAIF_NETDEV also needs to be
built as modules. You will also need to say yes to any CAIF physical
devices that your platform requires.
See Documentation/networking/caif for a further explanation on how to
use and configure CAIF.

depends on CAIF
default n
--- help ---
Enable the inclusion of debug code in the CAIF stack.
Be aware that doing this will impact performance.
If unsure say N.
config CAIF_NETDEV
tristate "CAIF GPRS Network device"
depends on CAIF
default CAIF
---help---
Say Y if you will be using a CAIF based GPRS network device.
This can be either built-in or a loadable module,
If you select to build it as a built-in then the main CAIF device must
also be a built-in.
If unsure say Y.
