This patch grew a lot, and that seems to be mainly because of bad reasons.
I'd suggest dropping the whole
"lockref_ret_count()"/"lockref_ret_lock()" helpers, which cause all
the annoyance, and just make people use the members directly.
Then, just do
#define d_lock d_lockref.lockref_lock
or similar, so that all the existing code just continues to work,
without the need for the syntactic changes:
- spin_lock(&dentry->d_lock);
+ d_lock(dentry);
For d_count, we probably do need to have the wrapper macro:
#define dentry_count(dentry) ((dentry)->d_lockref.lockref_count)
and change the existing users of "dentry->d_count" to use that, but
there are fewer of those than there are of people taking the dentry
lock. And most of them are in fs/dcache.c and would be affected by
this set of patches anyway.
