2014-07-12	add a size argument to free. will be used soon, but for now default to 0.	Ted Unangst
	after discussions with beck deraadt kettenis.
2014-07-08	decouple struct uvmexp into a new file, so that uvm_extern.h and sysctl.h	Theo de Raadt
	don't need to be married. ok guenther miod beck jsing kettenis
2014-03-28	Reduce uvm include madness. Use <uvm/uvm_extern.h> instead of	Martin Pieuchot
	<uvm/uvm.h> if possible and remove double inclusions. ok beck@, mlarkin@, deraadt@
2014-02-28	guenther's addition of filechk didn't take into account the different	Marc Espie
	structure of tmpfs_write. rewrite the opening tests to conform more to ffs's code, so that overrun is not used unitialized. Patch by kettenis@ (on the road) deraadt@ "do it right away"
2014-02-25	Check for offset wraparound and enforce RLIMIT_FSIZE.	Philip Guenther
	problem reported by brad@ ok kettenis@ millert@
2014-01-22	bring over kqfilter code from ufs which works better than the	Ted Unangst
	generic flavor. problems noted and tested by ajacoutot
2014-01-07	Delay checking the vnode locking of the target vnodes in tmpfs_rename()	Philip Guenther
	until we've confirmed they're on the same filesystem as the source: not all filesystems do locking the same. problem report and testing chrisz@ ok espie@
2013-12-25	zap defines that don't make any sense for us	Marc Espie
	okay tedu@
2013-12-23	sync specvops with ffs (fixing spec_open along the way)	Ted Unangst
	ok espie
2013-12-23	Move KASSERT a bit further down because it can apparently be triggered by	Mark Kettenis
	trying to hardlink a directory. While this is not allowed on tmpfs, this allows us to reach the code that checks for this such that we can return the appropriate error. Cluestick from Pedro Martelletto. ok espie@
2013-12-14	bring in a few improvements from pedro, guenther, me...	Marc Espie
	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@

2013-09-22	The readdir vop should set uio_offset to the cookie of the entry	Philip Guenther
	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@
2013-09-01	Update to match VOP_READDIR() changes: no more cookies, but d_off instead.	Philip Guenther
	Prodding and initial diff from espie@
2013-06-05	plug name_ipool leak in tmpfs_link()	Marc Espie
	from pedro.
2013-06-05	on drugs, did not read pedro's patch and just zapped the comment.	Marc Espie
	Obviously will not do... fixed
2013-06-04	restore code commented out while debugging. From pedro	Marc Espie

2013-06-04	fix include guard locations (from pedro)	Marc Espie

2013-06-04	Update pathconf handling for -current..	Brad Smith
	- Remove _PC_PATH_MAX, _PC_PIPE_BUF and _PC_SYNC_IO. - Add _PC_TIMESTAMP_RESOLUTION. - Change _PC_FILESIZEBITS from using "sizeof(off_t) * CHAR_BIT" to returning 64. With input from and Ok guenther@
2013-06-03	sprinkle $OpenBSD$, pointed out by pedro	Marc Espie

2013-06-01	import tmpfs code, originally from netbsd.	Marc Espie
	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@
