From 777e6bd706ee40897545463871de5b456fbc46dc Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Fri, 15 Aug 2008 15:34:15 -0400 Subject: Btrfs: Transaction commit: don't use filemap_fdatawait After writing out all the remaining btree blocks in the transaction, the commit code would use filemap_fdatawait to make sure it was all on disk. This means it would wait for blocks written by other procs as well. The new code walks the list of blocks for this transaction again and waits only for those required by this transaction.
