Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs fixes from Al Viro: "Followups to the parallel lookup work: - update docs - restore killability of the places that used to take ->i_mutex killably now that we have down_write_killable() merged - Additionally, it turns out that I missed a prerequisite for security_d_instantiate() stuff - ->getxattr() wasn't the only thing that could be called before dentry is attached to inode; with smack we needed the same treatment applied to ->setxattr() as well" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: switch ->setxattr() to passing dentry and inode separately switch xattr_handler->set() to passing dentry and inode separately restore killability of old mutex_lock_killable(&inode->i_mutex) users add down_write_killable_nested() update D/f/directory-locking

Locking scheme used for directory operations is based on two

kinds of locks - per-inode (->i_mutex) and per-filesystem

kinds of locks - per-inode (->i_rwsem) and per-filesystem

For our purposes all operations fall in 5 classes:

|

1) read access. Locking rules: caller locks directory we are accessing.

The lock is taken shared.

2) object creation. Locking rules: same as above.

4) rename() that is _not_ cross-directory. Locking rules: caller locks

it. If source is a non-directory, lock it. If that means we need to

lock both, lock them in inode pointer order.

RENAME_EXCHANGE in rename2() flags argument) lock both. In any case,

if the target already exists, lock it. If the source is a non-directory,
|
||||
lock it. If we need to lock both, lock them in inode pointer order.
|
||||
Then call the method. All locks are exclusive.
|
||||
NB: we might get away with locking the the source (and target in exchange
|
||||
case) shared.

5) link creation. Locking rules:

* lock parent
|

* check that source is not a directory
|
||||
* lock source
|

* call the method.
