@@ -126,6 +126,11 @@ flush_merge Merge concurrent cache_flush commands as much as possible
to eliminate redundant command issues. If the underlying
device handles the cache_flush command relatively slowly,
recommend to enable this option.
nobarrier This option can be used if underlying storage guarantees
its cached data should be written to the novolatile area.
If this option is set, no cache_flush commands are issued
but f2fs still guarantees the write ordering of all the
data writes.
