Fix the function get_victim_by_default, where it checks
for the condition that p.min_segno != NULL_SEGNO as
shown:
if (p.min_segno != NULL_SEGNO)
goto got_it;
and if above condition is true then
got_it:
if (p.min_segno != NULL_SEGNO) {
So this condition is being checked twice. Hence move the goto
statement after the if condition so that duplication of condition
check is avoided.
Also this function makes a call to get_max_cost() to compute
the max cost based on the f2fs_sbi_info and victim policy. Since
get_max_cost depends on on three parameters of victim_sel_policy
=> alloc_mode, gc_mode & ofs_unit, once this victim policy is
initialised, these value will not change till the execution
time of get_victim_by_default() & also f2fs_sbi_info structure
parameters will not change.
Hence making calls to get_max_cost() in while loop does not seems to
be a good point. Instead we can call it once in begining and store
the results in local variable, which later can serve our purpose
for comparing the cost with max cost inside the while loop.
