Subject: osdc/ObjectCacher.cc: set left to 0 instead off 'left -= left'
X-Git-Tag: v0.60~106^2~21
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=0517a2d537bad98b5975f930570ffbe2049ca45b;p=ceph.git

osdc/ObjectCacher.cc: set left to 0 instead off 'left -= left'

Instead of call 'left -= left', which results in 0, set left directly
to 0 and remove not needed assert call 'left == 0'.
