Subject: f2fs: report -ENOENT for unreached data indices
X-Git-Tag: v4.1-rc1~87^2~38
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=76629165913a6d5542bbe735191b021f31dd3798;p=karo-tx-linux.git

f2fs: report -ENOENT for unreached data indices

If inode has inline_data, it should report -ENOENT when accessing out-of-bound
region.
This is used by f2fs_fiemap which treats -ENOENT with no error.
