staging: usbip: vhci: handle EAGAIN from SO_RCVTIMEO
If there is a receive timeout without any active
requests, we can tell the connection was idle and
ignore the timeout.
If there are active requests for which we expect
to receive a reply we close the connection.
This makes it possible to set an upper bound on
the time a usbip device may be unresponsive.
This is a workaround for the lack of heart-beat
messages in the USBIP protocol.
Extending the protocol would break compatibility
with all previous stub versions, so this seems like
the lesser evil.

perf: Fix contexted inheritance
Linus reported that the RCU lockdep annotation bits triggered for this
rcu_dereference() because we're not holding rcu_read_lock().
Going over the code I cannot convince myself its correct:
- holding a ref on the parent_ctx, doesn't avoid it being uncloned
concurrently (as the comment says), so we can race with a free.
- holding parent_ctx->mutex doesn't avoid the above free from taking
place either, it would at best avoid parent_ctx from being freed.
I.e. the warning is correct. To fix the bug, serialize against the
unclone_ctx() call by extending the reach of the parent_ctx->lock.

x86: Make relocatable kernel work with new binutils
The CONFIG_RELOCATABLE=y option is broken with new binutils, which will make
boot panic.
According to Lu Hongjiu, the affected binutils are from 2.20.51.0.12 to
2.21.51.0.3, which are release since Oct 22 this year. At least ubuntu 10.10 is
using such binutils. See:
http://sourceware.org/bugzilla/show_bug.cgi?id=12327
The reason of the boot panic is that we have 'jiffies = jiffies_64;' in
vmlinux.lds.S. The jiffies isn't in any section. In kernel build, there is
warning saying jiffies is an absolute address and can't be relocatable. At
runtime, jiffies will have virtual address 0.

Btrfs: forced readonly mounts on errors
This patch comes from "Forced readonly mounts on errors" ideas.
As we know, this is the first step in being more fault tolerant of disk
corruptions instead of just using BUG() statements.
The major content:
- add a framework for generating errors that should result in filesystems
going readonly.
- keep FS state in disk super block.
- make sure that all of resource will be freed and released at umount time.
- make sure that fter FS is forced readonly on error, there will be no more
disk change before FS is corrected. For this, we should stop write operation.
After this patch is applied, the conversion from BUG() to such a framework can
happen incrementally.
