    Description

      Add ability to start GC for large changelogs if it affects filesystem free space. This will avoid running out of space on the MDT when the changelog grows very large, and will disable changelog entirely when the free space on the MDT becomes critically low, so that operations like unlink and rmdir will not report ENOSPC errors when trying to free space in the filesystem.
