+Subject: [PATCH 1/7] Use GMutex instead of GStaticMutex
+
+The static version was deprecated in GLib 2.32 [1], which was released
+on 2012-03-24 [2]. The difference between the two was that before
+2.32, GMutex could not be statically allocated. Since 2.32, GMutex
+can be statically allocated, so there's no reason to use GStaticMutex
+anymore.

+Subject: [PATCH 4/7] Use storageid to access storageArea
+
+'i' is indexing playlist->tracks here, and we don't want to look in a
+sequential storage areas for each track.
+
+I've also added a null-folder check. I'm not sure if -ENOENT is the
+right code for "we can't find the parent directory in the storage area
+that contains the child", but it's the only non-success code that
+mtpfs_getattr_real returned before this commit. And returning
+anything is probably better than segfaulting when we try and
+dereference folder with 'folder->parent_id'. I've added a logging
+message to help debug things when we do get a null folder.
