There is an issue in reserving and claiming space for localalloc, When localalloc space is not enough, it would claim space from global_bitmap. And if there is not enough free space in global_bitmap, the size of claiming space would set to half of orignal size and retry. The issue is as follows: osb->local_alloc_bits is set to half of orignal size in ocfs2_recalc_la_window(), but ac->ac_bits_wanted is set to osb->local_alloc_default_bits which is not changed. localalloc always reserves and claims local_alloc_default_bits space and returns ENOSPC. So, ac->ac_bits_wanted should be osb->local_alloc_bits which would be changed.
