From 222f1d69183f10d70a37de5785698fe0aa363c12 Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Mon, 16 Jan 2006 22:14:25 -0800 Subject: [PATCH] [PATCH] fuse: fuse_copy_finish() order fix fuse_copy_finish() must be called before request_end(), since the later might sleep, and no sleeping is allowed between fuse_copy_one() and fuse_copy_finish() because of kmap_atomic()/kunmap_atomic() used in them.
