cluster/afr: dir-write: Fix inode number handling.
create, mkdir, symlink, mknod: Prefer to return itransform'd inode number from the first_up_child. If not, fall back on any other child that returned succcess. link, rename: Return the same inode number that was passed as part of loc_t. Also adds a new member to afr_local_t, local->first_up_child which is initialized at the start of the transaction. This fixes the race where a subvolume might go down during the transaction and thus have the first_up_child change. Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 285 ("first up child" can change during a transaction) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=285
