Move to uint32_t for the relevant values. Aligned with FreeBSD changes. Also make sure newfs refuses to create an fs with more that 2^32-1 inodes. ok millert@ When the preferred cylinder group if full scan forward (wrapping if needed) 2020-05-29T06:46:15Z otto otto@openbsd.org 2020-05-29T06:46:15Z urn:sha1:458c9f6e6301be0ff829aee4a9cbebac06df8f8a to find another, instead of first forward and then backward. The latter method causes most full cgs to end up at the end of the partition. From FreeBSD. ok millert@ Make generation numbers unsigned and fill them using a random number 2020-05-28T15:48:28Z otto otto@openbsd.org 2020-05-28T15:48:28Z urn:sha1:d06c4e1f5435c136423f9e1463cd963b162d217f from the range [1..UINT_MAX] initially. On inode re-use increment and on wrap refill from the range [1..UINT_MAX-1] to avoid assigning UINT_MAX (the original value). Zero still means uninitialized. ok millert@ Use proper function to get a timestamp, as time_second isn't safe; 2020-02-21T11:13:55Z otto otto@openbsd.org 2020-02-21T11:13:55Z urn:sha1:faf38e4b7a80d680c602bcf8371b4b8b3dc5b64b ok cheloha@ getblk(9): tsleep(9) -> tsleep_nsec(9); ok visa@ 2019-07-19T00:24:31Z cheloha cheloha@openbsd.org 2019-07-19T00:24:31Z urn:sha1:570df5c46ec138c3c01140bbdb153f33c5d6314c Use arc4random_uniform() instead of arc4random() to avoid modulus bias. 2016-05-23T20:47:49Z tb tb@openbsd.org 2016-05-23T20:47:49Z urn:sha1:97653aec6885285ab7fb5e40fc242c19d1843487 This eliminates the idiom 'arc4random() % X' (where X + 1 is not a power of two) from base.
