Subject: [PATCH 4/5] ext4: remove unnecessary wait for extent conversion in ext4_fallocate()

From: Jan Kara <jack@...e.cz>

Now that we don't merge uninitialized extents anymore,
ext4_fallocate() is free to operate on the inode while there are still
some extent conversions pending - it won't disturb them in any way.
