Bruce Fields" Date: Wed, 8 Nov 2006 17:44:40 -0800 Subject: [PATCH] nfsd4: fix open-create permissions In the case where an open creates the file, we shouldn't be rechecking permissions to open the file; the open succeeds regardless of what the new file's mode bits say. This patch fixes the problem, but only by introducing yet another parameter to nfsd_create_v3. This is ugly. This will be fixed by later patches. Signed-off-by: J.

Therefore, this patch also removes all inline's from these files.
