    Description

      This adds the block allocator performance enhancement introduced in LU-12103 to CentOS 7.7, RHEL 8.x, Ubuntu 5.0 and 5.4 mainline kernels.

      —

      Block allocator uses some heuristic while choosing a group to allocate new blocks. This works good in most cases, but take a time for large low-free-space partition. The algorithm should be adjusted for this special case.
