ext4: Fix and simplify s_dirt handling
The s_dirt flag wasn't completely handled correctly, but it didn't really matter when journalling was enabled. It turns out that when ext4 runs without a journal, we don't clear s_dirt in places where we should have, with the result that the high-level write_super() function was writing the superblock when it wasn't necessary. So we fix this by making ext4_commit_super() clear the s_dirt flag, and removing many of the other places where s_dirt is manipulated. When journalling is enabled, the s_dirt flag might be left set more often, but s_dirt really doesn't matter when journalling is enabled. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
