afs_NewVCache was a twisty turny maze of #ifdefs and duplicated code.
This makes a number of sweeping changes to simplify this code, and to
move platform specific elements out into their own directories.
*) ShakeLooseVCaches is refactored so that the same code can be used
both for platforms that support dynamic vcaches, and those which
don't.
*) afs_NewVCache, ShakeLooseVCaches, and afs_AllocVCache are all
modified to remove platform specific code, and to call platform
specific functions.
*) A new platform file 'osi_vcache.c' is created to hold a number of
platform specific vcache operations:
*) osi_TryEvictVCache handles the decision of whether a vcache can
be evicted or not, and does so if required
*) osi_NewVnode allocates a new vnode
*) osi_PrePopulateVCache does the necessary population of the
vcache, before it's threaded onto the VLRUQ and associated hash
tables.
*) osi_AttachVnode handles attaching an OS vnode to our vcache,
where that is necessary
*) osi_PostPopulateVCache handles the vcache population that must
occur after we're on the VLRUQ and have a vnode attached.

# Developing Dynamically Loadable Kernel Modules
|
|
# Issue 1.0
|
|
# HP-UX 11.0
|
|
# October 12, 1998
|
|
#
|
|
# mentioned on http://docs.hp.com/hpux/os/index.html
|
|
# with URL http://docs.hp.com/hpux/content/dlkm_v1.2.pdf
|
|
#
|
|
# recommends the undocumented +ES1.Xindirect_calls option for both
|
|
# 32-bit and 64-bit kernel code, but it appears to be absolutely vital
|
|
# for compiling 64-bit kernel code. In 64-bit mode, the ANSI C compiler
|
|
# has the +Z (PIC) option on by default, and there is no documented way
|
|
# to turn it off. However, kernel code does not work properly when
|
|
# compiled with +Z (i.e. calling a function through a function pointer
|
|
# seems to hang). When the compiler sees the +ES1.Xindirect_calls
|
|
# option, however, it issues a warning and turns off +Z.
|
|
#
|
|
# for 11.23, see the DDK BE/Sample_makefiles/Makefile.bld
|
|
# for mod drivers.
|
|
#
|
|
# 11.23 uses new compiler, with new options. The same compiler is on pa_risc and ia64
