nfs_srvsock.c nfs_srvsubs.c
nfs_syscalls.c nfsm_subs.h
Log:
- Turn all explicit giant acquires into conditional VFS_LOCK_GIANTs.
Only ops which used namei still remained.
- Implement a scheme for reducing the overhead of tracking which vops
require giant by constantly reducing the number of recursive giant
acquires to one, leaving us with only one vfslocked variable.
- Remove all NFSD lock acquisition and release from the individual nfs
ops. Careful examination has shown that they are not required. This
greatly simplifies the code.
