"the latest 2.6 version of "tryflushdcachechildren" is probably
good enough for 2.2/2.4 as well. further, we can just call
d_invalidate() to make things less complicated. unification
is good.
its seen limited testing here under 2.4/2.6."

"ok, if you ever drop
dcache_lock you need to go to restart (i think that's pretty clear).
shrink_dcache_parent() _might_ reduce a dentry count to 0. in the
previous version, it seemed to make the assumption that this would
always happen. if shrink_dcache_parent() is unsuccessful and the
dentry is a directory, we cant restart. we would just find the
the dentry again and do the same thing over (we could always d_drop
but you shouldnt do this to active directories -- see d_invalidate).
if we find a busy dentry, we abort all processing for this inode.
going back to restart would find the same busy inode. (i suppose
we could use a d_flag to keep track of which dentry has been shrunk.
this has other trouble, like who resets the flag and when?) since we
only do this for directories and d_alias typically only grows due to
soft/hard links (as far as i can tell) this scheme seems reasonable."

"The new buffer code (which I wrote) did not deal
with dcache object re-use, as I had conflated the concepts of "dcache *
reuse" and "dcache slot reuse".
This patch should fix this problem. It now stores the dcache index (aka slot number,
which is the same as the numeric part of the cache file's filename) in the
buffer instead of the ephemeral struct dcache pointer."

Doug Engert reports that large tokens are corrupted when being sent
using RX. This patch fixes two bugs which prevent the transmission
and receipt of multiple packet exchanges.

"The changes I submitted previously, and committed as
linux-26-vlru-cycle-20041012 do not satisfy necessary invariants of the
dcache api.
1) the dcache_lock is not held when calling d_unhashed and
list_empty(&dentry->d_subdirs)
2) the caller of d_prune_aliases does not hold it's own ref on the inode

"lih_r now leaves the current lih_host held, and h_Releases those for which
it changed mind during h_Enumerate. It also closes the window that
ClearHostCallbacks_r opens.
The problem was: due to the leak on the h_Hold table, rx connections and
host and client structures stopped being garbage collected once the
fileserver went through GetSomeSpace_r. Only relevant for "busy" servers,
many would never even invoke this routine."

" the wake_up_bit() mechanism has replaced
'per object' wait queues (atleast when testing for single bit changes).
the actual wait queue to use is determined using a hash on page->flags
(which encodes the zone table in the lower 8 bits). afs inodes come from
a vmalloc() since afs gets all the inodes in one go. vmalloc()'d memory
apparently doesnt get mapped to any particular zone. so when an afs
inode uses wake_up_bit() they index off the end of the zone_page table.

* The variable used to determine whether a file or virtual memory
mapped cache is used was not properly initialized to a default
value. If the registry setting "NonPersistentCaching" was not
set, the choice would be random. Properly initialized to be
"file".
* The memory mapped view was never unmapped before closing the file
at service shutdown. This is now properly cleaned up.
* Default location of Cache file is now %TEMP%\AFSCache
