work. Not quite as good as with the Lite2 merges, but it'll do until then.
* dounmount() expects to be called with the mountpoint marked busy
* all callers of dounmount() thus make the call themselves
* if a filesystem was being unmounted, and we're woken up in vfs_busy(),
don't reference the mountpoint struct pointer, as it has very probably
been freed.
in the assembly file genassym.s into the usual assym.h file. The
assym.h file generated this way is identical to the output generated
if I simply compile and run the genassym.s file. "Heh, Kewl!"
Thanks to Matthias Pfaller for the "translate the .s file" idea!
* prototype it before it is used (several ports compile with
-Wstrict-prototypes -Wmissing-prototypes), so this is _necessary_.
* conform to C syntax (yes, that's right, it wouldn't parse).
* make error check less error-prone, + style fixups.
mount the root file system. If the operator specified the root
file system type in the kernel configuration file, attempt to
mount that file system type on the root device. If the root
file system type was wildcarded (or unspecified), try all of
the file systems statically built into the kernel until one
succeeds. If no file systems succeed, return an error. The
system will recover from this condition.
- Implement vfs_getopsbyname(). This function returns the file
system ops vector given a file system name.
from the version used by NetBSD/alpha, with several changes by me.
Support for asking for root device and root file system type on any
kernel, obsoleting "options GENERIC".
- Make my mountroothook implementation used by the sparc and x68k
ports machine-independent, and use it here. Mountroothooks allow
devices to execute special functions before being mounted as the
root device (such as ejecting the floppy and prompting for a new
floppy disk).
- Make swapconf() machine-independent. It was identical on all ports.
- Run mountroot hooks before we attempt to mount the root device, and
destroy mountroot hooks after the root file system has been sucessfully
mounted.
- Don't panic if we can't mount root. Instead, set RB_ASKNAME and
call setroot(), which will prompt the operator for the root device
and file system type.
is running (and NTP is not enabled), the adjtime()-handling code clobbers
any tickfix that may be necessary for systems with clocks with frequency
greater than 1000Hz.
Eliminate obsolete global kernel variable "struct timezone tz"
Add RTC_OFFSET option
Add global kernel variable rtc_offset, which is initialized by
RTC_OFFSET at kernel compile time.
on i386, x68k, mac68k, pc532 and arm32, RTC_OFFSET indicates how many
minutes west (east) of GMT the hardware RTC runs. Defaults to 0.
Places where tz variable was used to indicate this in the past have
been replaced with rtc_offset.
Add sysctl interface to rtc_offset.
Kill obsolete DST_* macros in sys/time.h
gettimeofday now always returns zeroed timezone if zone is requested.
settimeofday now ignores and logs attempts to set non-existant kernel
timezone.
* Fix arguments to various copyin()/copyout() invocations, to avoid
gratuitous casts.
* Some KNF formatting fixes
* Change sockargs()'s second argument to be a const void *, to help
with dealing with the syscall argument type fixups/const poisoning.
* change in-kernel syscall prototypes to match user-land prototypes in
the following ways:
+ add 'const' where appropriate.
+ make the following "safe" type changes where appropriate:
caddr_t -> struct msghdr *
caddr_t -> struct sockaddr *
caddr_t -> void *
char * -> void *
int -> uid_t (safe because uid_t not used as index/count)
int -> gid_t (safe because gid_t not used as index/count)
u_int -> size_t
+ change "int" to "u_long" in flags arguments to chflags() and
fchflags(). This is safe because the arguments are used as
flag bits and there's nothing that would cause the top bit
of the int to be set yet, and because the user-land definitions
already specified u_long, so a u_long's worth of argument was
already being passed in.
wrong for a bunch of functions:
void: sys_exit, sys_sync
ssize_t: sys_read, sys_write, sys_recvmsg, sys_sendmsg,
sys_recvfrom, sys_readv, sys_writev, sys_sendto
long: sys_pathconf, sys_fpathconf
void *: sys_shmat
* Note that sys_open, sys_ioctl, and sys_fcntl are defined such that their
last argument is optional.
These changes should not have any real effect, because right now this
information is not actually used for anything.
