commit 40ea98396a3659062267d1fe5f99af4f7e4f05e3 upstream.
When big allocate feature is enabled, we need to count and update
reserved clusters before removing a delayed only extent_status entry.
{init|count|get}_rsvd() have already done this, but the start block
number of this counting isn't correct in the following case.
lblk end
| |
v v
-------------------------
| | orig_es
-------------------------
^ ^
len1 is 0 | len2 |
If the start block of the orig_es entry founded is bigger than lblk, we
passed lblk as start block to count_rsvd(), but the length is correct,
finally, the range to be counted is offset. This patch fix this by
passing the start blocks to 'orig_es->lblk + len1'.
