---------------------------
-What: find_trylock_page
-When: January 2007
-Why: The interface no longer has any callers left in the kernel. It
- is an odd interface (compared with other find_*_page functions), in
- that it does not take a refcount to the page, only the page lock.
- It should be replaced with find_get_page or find_lock_page if possible.
- This feature removal can be reevaluated if users of the interface
- cannot cleanly use something else.
-Who: Nick Piggin <npiggin@suse.de>

What: Interrupt only SA_* flags
When: Januar 2007
Why: The interrupt related SA_* flags are replaced by IRQF_* to move them

- This option adds a `TCPMSS' target, which allows you to alter the
- MSS value of TCP SYN packets, to control the maximum size for that
- connection (usually limiting it to your outgoing interface's MTU
- minus 40).
-
- This is used to overcome criminally braindead ISPs or servers which
- block ICMP Fragmentation Needed packets. The symptoms of this
- problem are that everything works fine from your Linux
- firewall/router, but machines behind it can never exchange large
- packets:
- 1) Web browsers connect, then hang with no data received.
- 2) Small mail works fine, but large emails hang.
- 3) ssh works fine, but scp hangs after initial handshaking.
-
- Workaround: activate this option and add a rule to your firewall
- configuration like:
-
- iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN \
- -j TCPMSS --clamp-mss-to-pmtu

+ This option adds a `TCPMSS' target, which allows you to alter the
+ MSS value of TCP SYN packets, to control the maximum size for that
+ connection (usually limiting it to your outgoing interface's MTU
+ minus 40).
+
+ This is used to overcome criminally braindead ISPs or servers which
+ block ICMP Fragmentation Needed packets. The symptoms of this
+ problem are that everything works fine from your Linux
+ firewall/router, but machines behind it can never exchange large
+ packets:
+ 1) Web browsers connect, then hang with no data received.
+ 2) Small mail works fine, but large emails hang.
+ 3) ssh works fine, but scp hangs after initial handshaking.
+
+ Workaround: activate this option and add a rule to your firewall
+ configuration like:
+
+ iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN \
+ -j TCPMSS --clamp-mss-to-pmtu
