I noticed that btrfs fi defrag -c<method> can''t be used to compress files unless they are fragmented. This patch corrects the problem, by informing should_defrag_range if compression is enabled, and skipping tests for extent and adjacent extents if it is.

The inline/sparse extent check is not modified - I assumed it would not be useful to compress inline extents. -- Andrew Mahone andrew DOT mahone AT gmail DOT com\

This may or may not be of interest to CentOS developers; if it is not or if it is redundant of your efforts to keep atop of what's happening, you have my apologies. Whether it is joint or disjoint wrt to the upstream code is not known at this point, but I have submitted a request for elucidation if CERN security allows. kind regards/ldv ---------- Forwarded message ---------- From: Ewan
