Hello Lukas Czerner,
The patch 1f0e51771281: "ext4: Introduce FALLOC_FL_ZERO_RANGE flag
for fallocate" from Mar 18, 2014, leads to the following static
checker warning:
fs/ext4/extents.c:3653 ext4_split_convert_extents()
warn: odd binop '0x4 & 0x10'
fs/ext4/extents.c
3650 } else if (flags | EXT4_GET_BLOCKS_CONVERT) {
3651 split_flag |= ee_block + ee_len <= eof_block ?
3652 EXT4_EXT_MAY_ZEROOUT : 0;
3653 split_flag |= (EXT4_EXT_MARK_UNINIT2 & EXT4_EXT_DATA_VALID2);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This statement is a no-op. Probably | was intended?
3654 }
3655 flags |= EXT4_GET_BLOCKS_PRE_IO;
regards,
dan carpenter
