Subject: b=22252 allow multiple instances of the same nid in NID hash.
X-Git-Tag: 2.0.0.51~5
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=3bbdbcdc2d02a69d666a4e6a913511883a9ecd9c;ds=sidebyside

b=22252 allow multiple instances of the same nid in NID hash.

Case of multiple separate clients from the same NID (as with liblustre) is legitimate and so we
should allow multiple instances of the same NID in nid hash
