From: Gustavo Padovan Date: Tue, 31 May 2016 19:59:00 +0000 (-0300) Subject: staging/android: remove sw_sync.[ch] files X-Git-Tag: v4.8-rc1~193^2~104 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=d21858fdb3269e98aa62d522efec7ce2865368e6;p=linux.git staging/android: remove sw_sync.[ch] files We can glue the sw_sync file operations directly on the sync framework without the need to pass through sw_sync wrappers. It only builds sw_sync debugfs file support if CONFIG_SW_SYNC is enabled.
