* Finally removed the stat() and fstat() calls from the opendir() code.ru2012-03-021-24/+14
| | | | | | | | | | | They were made excessive in r205424 by opening with O_DIRECTORY. Also eliminated the fcntl() call used to set FD_CLOEXEC by opening with O_CLOEXEC. (fdopendir() still checks that the passed descriptor is a directory, and sets FD_CLOEXEC on it.) Reviewed by: ed

* In revision 231989, we pass a 16-bit clock ID into kernel, howeverdavidxu2012-02-252-21/+32
| | | | | | | | | | | | according to POSIX document, the clock ID may be dynamically allocated, it unlikely will be in 64K forever. To make it future compatible, we pack all timeout information into a new structure called _umtx_time, and use fourth argument as a size indication, a zero means it is old code using timespec as timeout value, but the new structure also includes flags and a clock ID, so the size argument is different than before, and it is non-zero. With this change, it is possible that a thread can sleep on any supported clock, though current kernel code does not have such a POSIX clock driver system.

* Globally replace u_int*_t from (non-contributed) man pages.ed2012-02-128-22/+22
| | | | | | | | | | | The reasoning behind this, is that if we are consistent in our documentation about the uint*_t stuff, people will be less tempted to write new code that uses the non-standard types. I am not going to bump the man page dates, as these changes can be considered style nits. The meaning of the man pages is unaffected. MFC after: 1 month
* Replace utxrm(8) by utx(8).ed2012-02-111-1/+1
| | | | | | | | | | At first, I added a utility called utxrm(8) to remove stale entries from the user accounting database. It seems there are cases in which we need to perform different operations on the database as well. Simply rename utxrm(8) to utx(8) and place the old code under the "rm" command. In addition to "rm", this tool supports "boot" and "shutdown", which are going to be used by an rc-script which I am going to commit separately.
