Subject: jfs: jump to error_out when filemap_{fdatawait, write_and_wait} fails
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7cfcd8b79ab2472102d9229863e86ff208f959d4;p=linux-beck.git

jfs: jump to error_out when filemap_{fdatawait, write_and_wait} fails

filemap_fdatawait/filemap_write_and_wait may fail, so check the return
value and jump to error_out in the case of error.
