Internal changelog: - Changed the signals code to match the new order of things. Also the new xtime_lock code needed to be picked up. It made some things a lot simpler. - Fixed a spin lock hand off problem in locking timers (thanks to Randy). - Fixed nanosleep to test for out of bound nanoseconds (thanks to Julie). - Fixed a couple of id deallocation bugs that left old ids laying around (hey I get this one). - This version has a new timer id manager. Andrew Morton suggested elimination of recursion (done) and I added code to allow it to release unused nodes. The prior version only released the leaf nodes. (The id manager uses radix tree type nodes.) Also added is a reuse count so ids will not repeat for at least 256 alloc/ free cycles. - The changes for the new sys_call restart now allow one restart function to handle both nanosleep and clock_nanosleep. Saves a bit of code, nice. - All the requested changes and Lindent too :). - I also broke clock_nanosleep() apart much the same way nanosleep() was with the 2.5.50-bk5 changes. TIMER STORMS The POSIX clocks and timers code prevents "timer storms" by not putting repeating timers back in the timer list until the signal is delivered for the prior expiry. Timer events missed by this delay are accounted for in the timer overrun count. The net result is MUCH lower system overhead while presenting the same info to the user as would be the case if an interrupt and timer processing were required for each increment in the overrun count. 2002-10-30T06:35:31Z Davide Libenzi davidel@xmailserver.org 2002-10-30T06:35:31Z urn:sha1:f751cfc01cc86a24d6266c7116cdc16f27e6da40 Latest version of the epoll interfaces. 2002-02-05T01:40:40Z Linus Torvalds torvalds@athlon.transmeta.com 2002-02-05T01:40:40Z urn:sha1:7a2deb32924142696b8174cdf9b38cd72a11fc96
