    autofs: don't bother with atomics for ino->count · 850d71ac
    Al Viro authored
    All writers are serialized on inode->i_rwsem.  So are the readers
    outside of expire.c.  And the readers in expire.c are in the
    code that really doesn't care about narrow races - it's looking
    for expiry candidates and its callers have to cope with the
    possibility of a good candidate becoming busy right under them.
    
    No point bothering with atomic operations - just use int and
    mark the non-serialized readers with READ_ONCE().
