Subject: f2fs: remove device type check for direct IO
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=dbf8e63f48af48f3f0a069fc971c9826312dbfc1;p=linux.git

f2fs: remove device type check for direct IO

To ensure serialized IOs, f2fs allows only LFS mode for zoned
device. Remove redundant check for direct IO.
