From f36f3042eae238bdaefe7c79310afe573bfc3622 Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Thu, 30 Jul 2009 10:04:48 -0400 Subject: Btrfs: be more polite in the async caching threads The semaphore used by the async caching threads can prevent a transaction commit, which can make the FS appear to stall. This releases the semaphore more often when a transaction commit is in progress.
