Subject: f2fs: fix to use more generic EOPNOTSUPP
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fd114ab22dd14ded1783b7f9b0aaddc14c098fe0;p=linux.git

f2fs: fix to use more generic EOPNOTSUPP

EOPNOTSUPP is widely used as error number indicating operation is
not supported in syscall, and ENOTSUPP was defined and only used
for NFSv3 protocol, so use EOPNOTSUPP instead.

Fixes: 0a2aa8fbb969 ("f2fs: refactor __exchange_data_block for speed up")
