From b94a8030583ac002d054234dd82bac48010bf108 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 4deff51bff616970dbb56fc5a88f226bb020dcbd.
