Subject: ext4: pass inode pointer instead of file pointer to punch hole
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=aeb2817a4ea99f62532adf3377be3b282d3bda12;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

No need to pass file pointer when we can directly pass inode pointer.
