Name:tg_iops_limit
Proto:static unsigned int tg_iops_limit(struct throtl_grp *tg, int rw)
Type:unsigned int
Parameter:
Type | Parameter | Name |
---|---|---|
struct throtl_grp * | tg | |
int | rw |
328 | blkg = tg_to_blkg(tg) |
336 | ret = internally used IOPS limits [rw][limit_index] |
337 | If ret == 0 && limit_index == LIMIT_LOW Then |
339 | If Not list_empty - tests whether a list is empty*@head: the list to test. || internally used bytes per second rate limits [rw][limit_index] Then Return UINT_MAX |
342 | Else Return MIN_THROTL_IOPS |
346 | If limit_index == LIMIT_MAX && internally used IOPS limits [rw][LIMIT_LOW] && internally used IOPS limits [rw][LIMIT_LOW] != internally used IOPS limits [rw][LIMIT_MAX] Then |
355 | Return ret |
Name | Describe |
---|---|
tg_update_has_rules | Set has_rules[] if @tg or any of its parents have limits configured.* This doesn't require walking up to the top of the hierarchy as the* parent's has_rules[] is guaranteed to be correct. |
throtl_trim_slice | Trim the used slices and adjust slice start accordingly |
tg_with_in_iops_limit | |
tg_may_dispatch | Returns whether one can dispatch a bio or not. Also returns approx number* of jiffies to wait before this bio is with-in IO rate and can be dispatched |
