X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2fc2bcc8d39945ac9e26114280d2b6d1e624825c;p=linux.git

f2fs: fix to check return value in f2fs_insert_range()

In f2fs_insert_range(), it missed to check return value of
filemap_write_and_wait_range(), fix it.

Meanwhile, just return error number once __exchange_data_block()
fails.
