commit: a96e5b90804be8b540d30f4a1453fc87f95b3149 From: OGAWA Hirofumi <[email protected]> Date: Mon, 18 Apr 2011 11:48:55 -0400 Subject: [PATCH] nfsd4: Fix filp leak
23fcf2ec93fb8573a653408316af599939ff9a8e (nfsd4: fix oops on lock failure) The above patch breaks free path for stp->st_file. If stp was inserted into sop->so_stateids, we have to free stp->st_file refcount. Because stp->st_file refcount itself is taken whether or not any refcounts are taken on the stp->st_file->fi_fds[].
