From 8216ef866df1119fd5a72372b8b29bce49c18590 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Thu, 28 Oct 2010 16:55:47 -0400 Subject: [PATCH] Btrfs: let the user know space caching is enabled If you mount -o space_cache, the option will be persistent across mounts, but to make sure the user knows that they did this, emit a message telling them if they didn't mount with -o space_cache but the feature is still used.
