Subject: LU-6924 ptlrpc: replay bulk request
X-Git-Tag: 2.7.58~6
X-Git-Url: https://git.whamcloud.com/?a=commitdiff_plain;h=0addfa9fa1d48cc9fa5eb05026848e55382f81a8;p=fs%2Flustre-release.git

LU-6924 ptlrpc: replay bulk request

Even though the server might already got the bulk
replay request, but bulk transfer timeout, let's
replay the bulk request, i.e. treat such replay as
same as no replied replay request (See
ptlrpc_replay_interpret()).
