Subject[PATCHv2 4/6] hfs: simplify a bit checking for R/O
Date
From: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

We have the following pattern in 2 places in HFS

if (!RDONLY)
hfs_mdb_commit();

This patch pushes the RDONLY check down to 'hfs_mdb_commit()'. This will
make the following patches a bit simpler.
