md-cache: fix time comparison to support 0 timeout

2012-04-02T18:25:12+00:00

The time comparison currently causes caching when the current
time matches the timeout. This causes caching to occur even
when the timeout parameter is set to 0. Fix the condition to
support the no caching scenario. A longer term approach is to
use gettimeofday() for more accurate granularity, but this
apparently fixes a known bug.

performance/write-behind: queue setattr fop with writes always.

2012-03-27T18:29:05+00:00

stat returned in setattr_cbk can be cached by the kernel. Hence it is
always necessary that we return correct stat, which implies that setattr
should not be out of order with respect to write fops.
