Subject: dm: don't report warning when doing deferred remove
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b7cce3e2cca9cd78418f3c3784474b778e7996fe;p=thirdparty%2Fkernel%2Fstable.git

dm: don't report warning when doing deferred remove

If dm_hash_remove_all was called from dm_deferred_remove, it would write
a warning "remove_all left %d open device(s)" if there are some other
devices active.

The warning is bogus, so let's disable it in this case.
