cluster/afr: Enable eager-lock

2012-03-18T06:31:38+00:00

Eager-lock is disabled by default.
Use cluster.eager-lock on/off to change the config.
write-behind on and eager-lock off is not supported configuration.

In afr, when eager-lock is enabled the inode lock on fd is taken
using the fd address as the lk-owner. So the lock is
interchangableale between the inode-locks on the same fd.

cluster/afr: handle sending NULL dentry name for inode link in self-heal-daemon

2012-03-14T10:53:35+00:00

* Without the dentry name, dentry cannot be created in inode_link, which
 leads to trying to access the null dentry to check if it is cyclic and
 thus segfault. So send the parent inode also NULL, which just returns
 the proper inode after assigning the gfid and type to the inode without
 trying to create dentry.

* Handle failures such as dentry_create returning NULL, in inode_link
  properly and return NULL in such cases.

* Increase the lru limit of inode table of self-heal-daemon to 2048

cluster/afr: Add new option to know which process it is in

2012-03-01T17:16:30+00:00

Afr xl needs to maintain inode-table inside the xl if it is in
self-heal-daemon. The code was depending on the option
self-heal-daemon to do this. This is wrong as the option can be
reconfigured to on/off. Added a new option which can't be
reconfigured for this purpose.

afr: [Un]Set the 'right' lkowner for [f]{inode|entry}_lk and the 'enclosed' fop.

2012-03-01T16:23:49+00:00

afr 'mangles' the lkowner inorder to ensure [f]inodelk/[f]entrylk fops from the
same application contend. But other fops that are 'visible' to the application
should operate with the lkowner provided by fuse for correct functioning of
posix-locks xlator.
