From ce71ec36840368b877fb63bd14c8e67ab62d08b1 Mon Sep 17 00:00:00 2001 From: Dave Hansen <haveblue@us.ibm.com> Date: Sat, 30 Sep 2006 23:29:06 -0700 Subject: [PATCH] r/o bind mounts: monitor zeroing of i_nlink Some filesystems, instead of simply decrementing i_nlink, simply zero it during an unlink operation. We need to catch these in addition to the decrement operations.
