NTFS: Release 2.0.6 - Major bugfix to make compatible with other kernel changes.
- Initialize the mftbmp address space properly now that there are more
fields in the struct address_space. This was leading to hangs and
oopses on umount since 2.5.12 because of changes to other parts of
the kernel. We probably want a kernel generic init_address_space()
function...
- Drop BKL from ntfs_readdir() after consultation with Al Viro. The
only caller of ->readdir() is vfs_readdir() which holds i_sem during
the call, and i_sem is sufficient protection against changes in the
directory inode (including ->i_size).
- Use generic_file_llseek() for directories (as opposed to
default_llseek()) as this downs i_sem instead of the BKL which is
what we now need for exclusion against ->f_pos changes considering we
no longer take the BKL in ntfs_readdir().

[PATCH] IDE PIO mode Fix
I found this bug in 2.5.10 first. And caused ext2 FS corruption.
We are porting Linux to PC-9801 architecture (made by NEC Japan).
It has PIO ONLY IDE I/F. So please check PIO mode too.
It was introduced in 2.5.9 and still exists in 2.5.13, and caused
superblock corruption for Andries. This fixes it.
Andrej Lajovic observes that in kd.h the definitions of K_NUMLOCK and
K_CAPSLOCK are interchanged. He is right (and this is the case since
1.1.54; nobody noticed because setleds.c does not use these defines).
So, here is the fix. No kernel behaviour is changed.

[PATCH] Do RPC over TCP reply message delivery in sock->data_ready()
xprt.c:
Speed up synchronous RPC over TCP calls by having the
replies delivered by the IPV4 "bottom half", instead of
switching to the rpciod process in order to call recvmsg().
- Remove sock_recvmsg() interface.
- Remove rpc_xprt_pending list and rpciod_tcp_dispatcher() interface.
- Use the new tcp_read_sock() interface to deliver data directly
from within tcp_data_ready().
sched.c:
- Remove references to rpciod_tcp_dispatcher.
xprt.h:
- New set of flags to reflect the TCP record read state.
i810-tco: Merge changes of the 2.4 kernel into the i810-tco module. Changes included are:
Support for 82801CA(M) chipset, timer margin needs to be > 3, support for WDIOC_SETTIMEOUT and WDIOC_GETTIMEOUT.
i810_rng: add support for other i8xx chipsets to the Random Number Generator module.
This is being done by adding the detection of the 82801E I/O Controller Hub.

[PATCH] 2.5.13: remove VALID_PAGE
This patch removes VALID_PAGE(), as the test was always too late for
discontinous memory configuration. It is replaced with pfn_valid()/
virt_addr_valid(), which are used to test the original input value.
Other helper functions:
pte_pfn() - extract the page number from a pte
pfn_to_page()/page_to_pfn() - convert a page number to/from a page struct

2.5.13 now has the generic tag support that I wrote included,

Fix the ide_tcq_invalidate_queue() WIN_NOP usage needed to clear
the internal queue on errors. It was disabled in the last

[PATCH] VM dirty page balancing
- The balance_dirty_pages() logic is simply wrong. It goes:
if (value > threshold)
go_and_write(value - threshold);
which is just fine for a single process writing data. But
for many processes, they *all* go and bring things back into
balance, and too much data gets written out.
- The
go_and_write(this much)
logic is inoperative, because I turned off the ->writeback_mapping()
function in ext2. So a call to writeback_unlocked_inodes(this_much)
doesn't actually decrement and test *this_much. It will walk every
inode, all the time. Silly.
So quickly fixing the above things, the amount of dirty+writeback
memory in the machine nicely stabilises at 500 megabytes across
the run.
