Does current thread have the exclusive access to newly allocated inode?
The chanllege comes from individual filesystem's -alloc_inode method.
It may exposure the inode to private lists, thus give other threads a chance
to access the inode.
That should not happen, however, because the inode is not
In insert_inode_locked4(), we call test() without i_lock held, it's
inconsistent with other places that calling test(). Though this
function is only used by reiserfs, in which case i_lock is unnecessary,
we should provide test() a consistent locking context.
This patch calls test() under the
At the beginning of fs/inode.c, the comment suggests both inode_hash_lock and
i_lock protect i_hash. I wonder why two locks are needed.
Grep the source code shows that i_hash is accessed in limited and
well-defined places:
1. In inode_unhashed()
2. In some special cases, as
Identity of an inode, which is defined by i_sb and i_ino or by individual
filesystem specific way, is not expected to be changed during inode's life
time. When identify an inode, taking i_lock _seems_ unnecessary. In source
code, we do have functions identifying an inode without i_lock held,
e.g.
This patchset optimizes several places which take the per inode spin lock.
They have not been fully tested yet, thus they are marked as RFC.
I do limited tests after all patches applied: use two 'find' to traverse the
filesystems and touch all files in parallel. This runs for several days in a

Hi Mel,
Thank you for this series. I have applied on clean 3.6-rc5 and tested, and
it works well for me - the lock contention is (still) gone and

Excellent!
