From: Artem Bityutskiy Date: Mon, 7 May 2012 15:45:39 +0000 (+0300) Subject: jffs2: remove unnecessary GC pass on umount X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c3c4a36979c8b68cc35643497e83c7383cd07955;p=linux-beck.git 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.
