From 4335723e8e9fdc6e4bb2555696bc7f1abe75f200 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Fri, 24 Jan 2014 18:04:40 -0500 Subject: [PATCH] nfsd4: fix delegation-unlink/rename race If a file is unlinked or renamed between the time when we do the local open and the time when we get the delegation, then we will return to the client indicating that it holds a delegation even though the file no longer exists under the name it was open under. But a client performing an open-by-name, when it is returned a delegation, must be able to assume that the file is still linked at the name it was opened under. So, hold the parent i_mutex for longer to prevent concurrent renames or unlinks. Signed-off-by: J. Bruce Fields --- Reading git-format-patch failed
