* [NET]: Adding SO_TIMESTAMPNS / SCM_TIMESTAMPNS supportEric Dumazet2007-04-26
| | | | | | | | | | | | | | | | | | | | | Now that network timestamps use ktime_t infrastructure, we can add a new SOL_SOCKET sockopt SO_TIMESTAMPNS. This command is similar to SO_TIMESTAMP, but permits transmission of a 'timespec struct' instead of a 'timeval struct' control message. (nanosecond resolution instead of microsecond) Control message is labelled SCM_TIMESTAMPNS instead of SCM_TIMESTAMP A socket cannot mix SO_TIMESTAMP and SO_TIMESTAMPNS : the two modes are mutually exclusive. sock_recv_timestamp() became too big to be fully inlined so I added a __sock_recv_timestamp() helper function.

* [NET]: Introduce SIOCGSTAMPNS ioctl to get timestamps with nanosec resolutionEric Dumazet2007-04-26
| | | | | | | | | | Now network timestamps use ktime_t infrastructure, we can add a new ioctl() SIOCGSTAMPNS command to get timestamps in 'struct timespec'. User programs can thus access to nanosecond resolution. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> CC: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S.

* | | [PATCH] consolidate line discipline number definitionsTilman Schmidt2007-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The line discipline numbers N_* are currently defined for each architecture individually, but (except for a seeming mistake) identically, in asm/termios.h. There is no obvious reason why these numbers should be architecture specific, nor any apparent relationship with the termios structure. The total number of these, NR_LDISCS, is defined in linux/tty.h anyway. So I propose the following patch which moves the definitions of the individual line disciplines to linux/tty.h too. Three of these numbers (N_MASC, N_PROFIBUS_FDL, and N_SMSBLOCK) are unused in the current kernel, but the patch still keeps the complete set in case there are plans to use them yet.

* | | [PATCH] kill eth_io_copy_and_sum()Al Viro2007-02-09
|/ / | | | | | | | | | | | | | | | | | | | | On all targets that sucker boils down to memcpy_fromio(sbk->data, from, len). The function name is highly misguiding (it _never_ does any checksums), the last argument is just a noise and simply expanding the call to memcpy_fromio() gives shorter and more readable source. For a lot of reasons it has almost no remaining users, so it's better to just outright kill it.

* | [ARM] pass vma for flush_anon_page()Russell King2007-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since get_user_pages() may be used with processes other than the current process and calls flush_anon_page(), flush_anon_page() has to cope in some way with non-current processes. It may not be appropriate, or even desirable to flush a region of virtual memory cache in the current process when that is different to the process that we want the flush to occur for. Therefore, pass the vma into flush_anon_page() so that the architecture can work out whether the 'vmaddr' is for the current process or not. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* | [PATCH] Optimize D-cache alias handling on forkRalf Baechle2006-12-13

* | [PATCH] tty: preparatory structures for termios revampAlan Cox2006-12-08
|/ | | | | | | | | | | | | | | | | | | | In order to sort out our struct termios and add proper speed control we need to separate the kernel and user termios structures. Glibc is fine but the other libraries rely on the kernel exported struct termios and we need to extend this without breaking the ABI/API To do so we add a struct ktermios which is the kernel view of a termios structure and overlaps the struct termios with extra fields on the end for now. (That limitation will go away in later patches). Some platforms (eg alpha) planned ahead and thus use the same struct for both, others did not. This just adds the structures but does not use them, it seems a sensible splitting point for bisect if there are compile failures (not that I expect them) Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
