* bring in a few improvements from pedro, guenther, me...espie2013-12-145-527/+360
| | | | | | | | | | | | | | thanks to krw@ for the original cherry-picking, millert@ for useful comment. so: - no longer expose internal kernel addresses, uses seq numbers instead - make sure the numbers don't overflow (millert@ UINT64_MAX)... a conservative estimate is that tmpfs will run out of seqs in >600 years... - don't malloc dents, put them on the stack and zero them - gc whiteout code - gc getpage/putpage code (shrink uvm instead) okay krw@, millert@

* The readdir vop should set uio_offset to the cookie of the entryguenther2013-09-223-19/+17
| | | | | | | | | | after the last entry that fit, but I had it setting it to the cookier of the entry after that, so it would skip one entry for each block required. Remove the no-longer-needed cnt/cntp variable while we're touching things. prodding and testing by espie@
* Update to match VOP_READDIR() changes: no more cookies, but d_off instead.guenther2013-09-012-68/+31

heavy lifting by Pedro Martelletto, timestamp fixes by me. THIS IS NOT ENABLED YET, AND REQUIRES UVM CHANGES AND REVIEW. Imported, so that working on it can be mostly done in tree with less painful diff exchanges, and that we have history of further changes. okay tedu@, deraadt@
