self-decompressing ram disk that I'm fiddling with..
(Note, this depends on the various syscalls having correctly set uio_segflag
before calling physio - I've checked and they look correct.)
What was happening, was that the main mfs loop was sleeping, and when it was
being awoken by a wakeup when it was supposed to process some IO requests.
The problem was that if it was being woken out of the tsleep() by a signal
at shutdown, it was going straight into dounmount() without servicing any
pending IO requests, causing dounmount() to fail because there were busy
buffers (and they could not be "processed" because the processing loop was
trying to unmount rather than dispatching into mfs_doio()).
This (dare I say it :-) appears to be a layering problem....
too. Basically, if the name starts with a "/", it's tested with "test -e";
otherwise, it's tested with "witch -s".
Reviewed by: the ports list (well at least nobody complained)
Changed beforeinstall rule to use `install -C' instead of `cmp -s'
and `install -c'. `install -C' has exactly the right semantics
for installing headers and should be used elsewhere.
cleaning during a make. This may give you more rope to hang yourself if
you are caught with some subtle dependency on installed binaries in your
build, but if you are doing daily 'make -DNOCLEAN world' it's not too bad
at all. It could take as little as 30 minutes to do an entire sync-up of
your binaries if everything's up to date, especially if you are using
'INSTALL=install -C' in /etc/make.conf (highly recomended!).
Also, add a "reinstall" target. You can do a 'make DESTDIR=/mnt reinstall'
where /mnt is the nfs root of a machine and you get the install parts of
the make world run on it.
I saw this on -hackers quite some time ago and included it in my Makefile
and have been using it on and off for a while. Alas, I cannot find the
actual message with the author's name...
to get the prototypes.
Changed some `int's to `boolean_t's. boolean_t's are ints so they are
hard to distinguish from ints.
Converted function headers to old-style. ddb is written in K&R1 C
except where we broke it.
- don't #include other headers just to get struct names.
- don't use __BEGIN_DECLS/__END_DECLS for system prototypes. It is for
user prototypes.
- don't use extern.
- don't use lines longer than 80 columns.
- use alphabetical order.
- use tabs.
Uniformized idempotency ifdefs.
it `const' to inhibit compiler warnings.
Added #include of <pccard/driver.h> to get prototypes. <pccard/slot.h>
is still necessary for its side effect of exporting non-slot things.
