Subject: f2fs: return i_size if the hole is outside of i_size
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fe369bc8ba205537864cb86ba08b390ad20201c4;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

When SEEK_HOLE is requeted, it should return i_size if the hole position is
found outside of i_size.
