[PATCH 0/7] btrfs: fix periodic reclaim condition with some cleanup

[Sun YangKai <sunk67188@gmail.com>]

This series eliminates wasteful periodic reclaim operations that were occurring
when already failed to reclaim any new space, and includes several preparatory
cleanups.

Patch 1-6 are non-functional changes.

Patch 7 fixes the core issue, details are in the commit message.

Thanks.
