[Cluster-devel] [PATCH] gfs2: Make sure we don't miss any delayed withdraws

[Bob Peterson <rpeterso@redhat.com>]

----- Original Message -----
> Commit ca399c96e96e changes gfs2_log_flush to not withdraw the
> filesystem while holding the log flush lock, but it fails to check if
> the filesystem needs to be withdrawn once the log flush lock has been
> released.  Likewise, commit f05b86db314d depends on gfs2_log_flush to
> trigger for delayed withdraws.  Add that and clean up the code flow
> somewhat.
> 
> In gfs2_put_super, add a check for delayed withdraws that have been
> missed to prevent these kinds of bugs in the future.

> Fixes: ca399c96e96e ("gfs2: flesh out delayed withdraw for gfs2_log_flush")
> Fixes: f05b86db314d ("gfs2: Prepare to withdraw as soon as an IO error occurs
> in log write")
