Add support for O_TMPFILE Linux 3.11 add O_TMPFILE to open(2), which allow creating an unlinked file on supported filesystem. It's basically doing open(2) and unlink(2) atomically. The filesystem support is added through i_op->tmpfile. We basically copy the create operation except we get rid of the link and name related stuff and add the new node to unlinked set. We also add support for linkat(2) to link tmpfile. However, since all previous file operation will skip ZIL, we force a txg_wait_synced to make sure we are sync safe.

Rename zfs_sb_t -> zfsvfs_t The use of zfs_sb_t instead of zfsvfs_t results in unnecessary conflicts with the upstream source. Change all instances of zfs_sb_t to zfsvfs_t including updating the variables names. Whenever possible the code was updated to be consistent with hope it appears in the upstream OpenZFS source.

port async unlinked drain from illumos-nexenta This patch is an async implementation of the existing sync zfs_unlinked_drain() function. This function is called at mount time and is responsible for freeing znodes that we didn't get to freeing before. We don't have to hold mounting of the dataset until the unlinked list is fully drained as is done now. Since we can process the unlinked set asynchronously this results in a better user experience when mounting a dataset with entries in the unlinked set.
