From c959df9f01cfb2f43b4d1f58631ee1e9c50541b6 Mon Sep 17 00:00:00 2001 From: Latchesar Ionkov Date: Mon, 23 Apr 2007 14:41:11 -0700 Subject: v9fs: don't use primary fid when removing file v9fs_insert uses v9fs_fid_lookup (which also locks the fid) to get the primary fid associated with the dentry and destroys the v9fs_fid struct after removing the file. If another process called v9fs_fid_lookup on the same dentry, it may wait undefinitely for the fid's lock (as the struct is freed). This patch changes v9fs_remove to use a cloned fid, so the primary fid is not locked and freed.
