Analyze and fix the following issue in the Linux kernel code: Add a dentry op to allow processes to be held during pathwalk transit
Problem Details: Add a dentry op (d_manage) to permit a filesystem to hold a process and make it sleep when it tries to transit away from one of that filesystem's directories during a pathwalk. The operation is keyed off a new dentry flag (DCACHE_MANAGE_TRANSIT). The filesystem is allowed to be selective about which ...

Analyze and fix the following issue in the Linux kernel code: do_lookup() fix
Problem Details: do_lookup() has a path leading from LOOKUP_RCU case to non-RCU crossing of mountpoints, which breaks things badly. If we hit need_revalidate: and do nothing in there, we need to come back into LOOKUP_RCU half of things, not to done: in non-RCU one. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
