    Btrfs: fix off-by-one logic error in btrfs_realloc_node · 5dfe2be7

    The end_slot variable actually matches the number of pointers in the
    node and not the last slot (which is 'nritems - 1'). Therefore in order
    to check that the current slot in the for loop doesn't match the last
    one, the correct logic is to check if 'i' is less than 'end_slot - 1'
    and not 'end_slot - 2'.
    
    Fix this and set end_slot to be 'nritems - 1', as it's less confusing
    since the variable name implies it's inclusive rather then exclusive.
