| Doc Text: |
When GFS2 grew the file system, it never reread the rindex file during the grow. This is necessary for large grows when the file system is almost full, and GFS2 needs to use some of the space allocated earlier in the grow to complete it. Now, if GFS2 fails to reserve the necessary space and the rindex data is not up-to-date, it rereads it, fixing this bug.

Created attachment 467867 [details] patch to fix rindex growing and truncating problems. This patch does a couple of things. 1. It removes gfs2_ri_update_special(), since gfs2_ri_update() works correctly for all callers. 2. It calls gfs2_ri_update() if the rindex list is not uptodate, and gfs2 runs out of space growing the rindex file. This allows you to use space allocated earlier in the grow to finish the grow. 3. It keeps do_strip() from grabbing the rindex glock, if it is working on the rindex file. This allows you to truncate the rindex file.
