While touching all vptofh/fhtovp functions, get rid of VFS_MAXFIDSIZ,
version the getfh(2) syscall and explicitly pass the size available in
the filehandle from userland.
Discussed on tech-kern, with lots of help from yamt (thanks!).
matter how empty they are.
Note that if two blocks have the same inode and block number, they sort
the same (this should never happen, but if it does there's no reason to
have qsort scramble the list).
Add some diagnostic syslog messages for unusual cases.
In determining when to stop reading segments when counting bytes (-b flag),
total the sizes of the blocks we're actually writing instead of assuming
they are all full blocks: many could be fragments or inode blocks. This
increases the number of segments per Ifile write, markedly improving the
efficiency of the cleaner in the small file case.
indirect block when considering the cleaning of block numbers less
than NDADDR (which do not use indirect blocks).
Also, note the loss of only half a block per segment to fragmentation
when considering the benefit function, rather than a whole block.
- avoid double slashes when displaying man pages (got tired
of '/usr/share/man//cat1/man.0').
- got rid of __P() while working on it.
- incorporate some of my old notes explaining how manpath works into the
comments of the code itself.
- renamed some of the vars so that the code is consistent throughout
(and hopefully clearer and easier to understand)
- fixed relative man paths for multiple man pages (man did a chdir()
on the first man page it had to format --- this broke any remaining
relative path man pages left to process). save old directory and
fchdir() back to it after formatting.
- improved doc on "man -h" which does more than just whatis(1) [e.g.
"man -h fopen" prints the required include files and the prototypes
rather than just the one-liner you get with whatis(1)]
- manconf.c now fills in the "len" length field in the TAG/ENTRY
structures (man now uses len).
revise man.conf file reading stuff to return error on failure in
addentry/gettag (fka getlist) rather than just err()ing out. this
allows man(1) to call cleanup and delete its tmp files rather than
just leave them floating. revise other apps using this code
(makewhatis, apropos, catman, whatis) to expect this. also remove
__P on updated files.
cleaner, but with more legible code.
Includes code for reading and writing to the raw disk device (so that an
unmounted fs could be cleaned), for the use of a single daemon to clean
multiple filesystems to save on resources, and for recording the old
contents of cleaned segments to offline storage for regression testing of
the LFS system as a whole; though these new features are not properly
tested at this point.
free() call, change the allocation policy to leave the responsibility for
allocation/freeing the pathname to _rtld_map_object(), instead of having
the caller allocate it and _rtld_map_object() free it. This simplifies the
code a lot and it is more efficient.
"Fix a bug that showed up when debugging dynamically linked programs.
References from GDB to "printf" and various other functions would
find the versions in the dynamic linker itself, rather than the
versions in the program's libc. This fix moves the GDB link map
entry for the dynamic linker to the end of the search list, where
its symbols will be found only if they are not found anywhere else."
"printf" isn't true for us, but various libc symbols are, e.g. "malloc".

declaration too.
32-bit SuperH can not pretend that _GLOBAL_OFFSET_TABLE_ is a normal
variable, because of the way PIC variable references is generated, but
as compiler arranges for _GLOBAL_OFFSET_TABLE_ address to be in r12
anyway, just use that value by declaring it as a global register
variable. Makes sh3 compile with RTLD_DEBUG.
_rtld_find_symdef use _rtld_symlook_default.
This reduces the code size and means that dlsym(RTLD_DEFAULT,...) has the
correct lookup order.

only the second part of the previous revision was needed.
put the logic for the initial icache invalidation of the PLT
back the way it was, but in a way that makes clearer what's going on,
and add some comments explaining it.
This allows for setting the passive socket's SO_RCVBUF. Option works
similarly to the current sendbufsize configuration option.
* Change how recveive_data() works
When reading data from the socket for passive transfers to the server,
receive_data() now works very similar to send_data_with_read(). Reads
from the network are now done using either the filesystem block size or
the configuration option readsize chunks.
* Crank version.h
[Changes discussed with lukem.]
ftpd will listen on the default FTP port for incoming connections and fork
a child for each connection. This is lower overhead than starting ftpd from
inetd(8) and thus might be useful on busy servers to reduce load.
Inspired by FreeBSD.
