With TWRP, on almost every operation I get 

> Failed to mount '/preload' (Invalid argument)

My device currently can not boot, and this may have something to do with it, `/preload` is currently in `/etc/fstab`, I can see the entry here with

    /dev/block/mmcblk0p16 /preload ext4 rw 0 0

When I try to mount it, I get

    mount preload/
    mount: mounting /dev/block/mmcblk0p16 on /preload failed: Invalid argument

Is there anyway to fix this problem?

From my `recovery.log`, I have

    /preload | /dev/block/mmcblk0p16 | Size: 0MB Used: 0MB Free: 0MB Backup Size: 0MB
       Flags: Can_Be_Mounted Can_Be_Wiped IsPresent 
       Primary_Block_Device: /dev/block/mmcblk0p16
       Display_Name: preload

       Storage_Path: /preload
       Current_File_System: ext4
       Fstab_File_System: ext4

I'm trying to flash LineageOS, but I'm really just curious about resolving this error message.
