Hello, What will happen if I forgot to allow_write_access() and fput()? The kernel 2.6.9 has this bug. (From 2.6.10 are OK.) http://www.cs.wisc.edu/~vikas/lxr/http/source/fs/exec.c#L1113 http://lxr.linux.no/source/fs/exec.c?v=2.6.10#L1118 I made a private patch for 2.6.9 and applied the patch to a customer's system for 2.6.11, so the patch inherited this bug. I have to explain what will happen to the customer. For example, (A) Cannot replace executable files by 'rpm -Uvh'. (B) Causes memory leak. (C) Nothing harmful.
