From c3c4a36979c8b68cc35643497e83c7383cd07955 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Mon, 7 May 2012 18:45:39 +0300 Subject: [PATCH] jffs2: remove unnecessary GC pass on umount We do not need to call 'jffs2_write_super()' on unmount. This function causes a GC pass to make sure the current contents is pushed out with the data which we already have on the media. But this is not needed on unmount and only slows unmount down unnecessarily. It is enough to just sync the write-buffer. This call was added by one of the generic VFS rework patch-sets, see 8c85e125124a473d6f3e9bb187b0b84207f81d91.
