Subject: f2fs: fix to check return value __allocate_new_segment
X-Git-Tag: v6.9-rc1~67^2~13
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=28f66cc654039edff3e34200c3357d92a7c4d272;p=thirdparty%2Fkernel%2Flinux.git

f2fs: fix to check return value __allocate_new_segment

__allocate_new_segment may return error when get_new_segment
fails, so its caller should check its return value.
