This prevents retired blocks from being played back when there is no
checkpoint and the nand driver could not mark the block as bad.

Without this we will crash in fput if the first mmap gets unmapped
before the second mmap starts.

Add a family of knobs to /sys/kernel/ipv4 for controlling the TCP window size:

	tcp_wmem_min
	tcp_wmem_def
	tcp_wmem_max
	tcp_rmem_min
	tcp_rmem_def
	tcp_rmem_max

This six values mirror the sysctl knobs in /proc/sys/net/ipv4/tcp_wmem and
/proc/sys/net/ipv4/tcp_rmem.

Sysfs, unlike sysctl, allows us to set and manage the files' permissions and
owners.

When we resume we only know how many whole seconds has elapsed.
These errors would accumulate in delta. We now only set the delta
if it would change by more than two seconds. If we drift back by
by more than a second add one in resume.

The conversion between virtual and real time is as follows:

  dvt = rw/w * dt <=> dt = w/rw * dvt

Since we want the fair sleeper granularity to be in real time, we actually
need to do:

dvt = - rw/w * l

This bug could be related to the regression reported by Yanmin Zhang:

| Comparing with kernel 2.6.25, sysbench+mysql(oltp, readonly) has lots
| of regressions with 2.6.26-rc1:

| 1) 8-core stoakley: 28%;
| 2) 16-core tigerton: 20%;
| 3) Itanium Montvale: 50%.
