| H A D | extents.c | d1e18b88 Thu Oct 08 10:02:48 CDT 2020 Ritesh Harjani <riteshh@linux.ibm.com> ext4: fix bs < ps issue reported with dioread_nolock mount opt
left shifting m_lblk by blkbits was causing value overflow and hence
it was not able to convert unwritten to written extent.
So, make sure we typecast it to loff_t before do left shift operation.
Also in func ext4_convert_unwritten_io_end_vec(), make sure to initialize
ret variable to avoid accidentally returning an uninitialized ret.
This patch fixes the issue reported in ext4 for bs < ps with
dioread_nolock mount option.
