  • Function-scope statics are discouraged because they are
    easily overlooked and can cause subtle bugs/races due to
    their global (non-SMP safe) nature.

    make the const.

  • root_task_group is the leftover of USER_SCHED, now it's always
    same to init_task_group.
    But as Mike suggested, root_task_group is maybe the suitable name
    to keep for a tree.
    So in this patch:
    init_task_group --> root_task_group
    init_task_group_load --> root_task_group_load
    INIT_TASK_GROUP_LOAD --> ROOT_TASK_GROUP_LOAD

  • Reduce some branches and memory accesses in dcache lookup by adding dentry
    flags to indicate common d_ops are set, rather than having to check them.
    This saves a pointer memory access (dentry->d_op) in common path lookup
    situations, and saves another pointer load and branch in cases where we
    have d_op but not the particular operation.

    Patched with:

    git grep -E '[.>]([[:space:]])*d_op([[:space:]])*=' | xargs sed -e 's/\([^\t ]*\)->d_op = \(.*\);/d_set_d_op(\1, \2);/' -e 's/\([^\t ]*\)\.d_op = \(.*\);/d_set_d_op(\&\1, \2);/' -i

  • dget_locked was a shortcut to avoid the lazy lru manipulation when we already
    held dcache_lock (lru manipulation was relatively cheap at that point).
    However, how that the lru lock is an innermost one, we never hold it at any
    caller, so the lock cost can now be avoided. We already have well working lazy
    dcache LRU, so it should be fine to defer LRU manipulations to scan time.

  • Protect d_subdirs and d_child with d_lock, except in filesystems that aren't
    using dcache_lock for these anyway (eg. using i_mutex).

    Note: if we change the locking rule in future so that ->d_child protection is
    provided only with ->d_parent->d_lock, it may allow us to reduce some locking.
    But it would be an exception to an otherwise regular locking scheme, so we'd
    have to see some good results. Probably not worthwhile.

  • Make d_count non-atomic and protect it with d_lock. This allows us to ensure a
    0 refcount dentry remains 0 without dcache_lock. It is also fairly natural when
    we start protecting many other dentry members with d_lock.

  • Change d_delete from a dentry deletion notification to a dentry caching
    advise, more like ->drop_inode. Require it to be constant and idempotent,
    and not take d_lock. This is how all existing filesystems use the callback
    anyway.

    This makes fine grained dentry locking of dput and dentry lru scanning
    much simpler.

  • Switching d_op on a live dentry is racy in general, so avoid it. In this case
    it is a negative dentry, which is safer, but there are still concurrent ops
    which may be called on d_op in that case (eg. d_revalidate). So in general
    a filesystem may not do this. Fix cgroupfs so as not to do this.
