Fixed
-----
Tulip hang on rmmod (fixed in .51 ?)
Incredibly slow loopback tcp bug (believed fixed about 2.3.48)
COMX series WAN now merged
VM needs rebalancing or we have a bad leak
SHM works chroot
SHM back compatibility
Intel i960 problems with I2O
Symbol clashes and other mess from _three_ copies of zlib!
PCI buffer overruns
Shared memory changes change the API breaking applications (eg gimp)
Finish softnet driver port over and cleanups
via rhine oopses under load ?
SCSI generic driver crashes controllers (need to pass PCI_DIR_UNKNOWN..)
 
In Progress
-----------
Merge the network fixes  (DaveM)
Merge 2.2.15 changes     (Alan)
Get RAID 0.90 in         (Ingo)
 
Fix Exists But Isnt Merged
--------------------------
Signals leak kernel memory (security)
msync fails on NFS
Semaphore races
Semaphore memory leak
Exploitable leak in file locking
Merge the RIO driver (probably do post 2.4.0 as it is large) (in AC tree)
S/390 Merge (merged in AC tree)
1.07 AMI MegaRAID
Any user can crash FAT fs code with ftruncate
Mark SGI VisWS obsolete
 
To Do
-----
Restore O_SYNC functionality
Fix eth= command line
Trace numerous random crashes in the inode cache
Fix Space.c duplicate string/write to constants
VM kswapd has some serious problems
vmalloc(GFP_DMA) is needed for DMA drivers
put_user appears to be broken for i386 machines
Fix module remove race bug              (mostly done - Al Viro)
Test other file systems on write 
Security holes in execve()
Directory race fix for UFS
Audit all char and block drivers to ensure they are safe with the 2.3
        locking - a lot of them are not especially on the open() path.
Stick lock_kernel() calls around driver with issues to hard to fix nicely
        for 2.4 itself
IDE fails on some VIA boards (eg the i-opener)
PCMCIA/Cardbus hangs, IRQ problems, Keyboard/mouse problem (may be fixed ?)
Use PCI DMA by default in IDE is unsafe (must not do so on via VPx x<3)
Use PCI DMA 'lost interrupt' problem with some hw [which ?]
Crashes on boot on some Compaqs ?
pci_set_master forces a 64 latency on low latency setting devices.Some
        boards require all cards have latency <= 32
usbfs hangs on mount sometimes
Loopback fs hangs
Problems with ip autoconfig according to Zaitcev
Still some SHM bug reports
SMP affinity code creates multiple dirs wit the same name
TLB flush should use highest priority
Set SMP affinity mask to actual cpu online mask (needed for some boards)
pci_socket crash on unload
 
To Do But Non Showstopper
-------------------------
Make syncppp use new ppp code
Finish 64bit vfs merges (lockf64 and friends missing)
NCR5380 isnt smp safe
DMFE is not SMP safe
ACPI hangs on boot for some systems
Get the Emu10K merged
Finish I2O merge
Go through as 2.4pre kicks in and figure what we should mark obsolete for
        the final 2.4
Per Process rtsigio limit
Fix SPX socket code
Boot hangs on a range of Dell docking stations (Latitude)
HFS is still broken
iget abuse in knfsd
Mark NTFS as obsolete
Paride seems to need fixes for the block changes yet
PIII FXSAVE/FXRESTORE support
Some people report 2.3.x serial problems
AIC7xxx doesnt work non PCI ?
USB hangs on APM suspend on some machines
PCMCIA crashes on unloading pci_socket
DEFXX driver appears broken
ISAPnP IRQ handling failing on SB1000 + resource handling bug
 
Compatibility Errors
--------------------
exec() returns wrong codes on a file not found
 
Probably Post 2.4
-----------------
per super block write_super needs an async flag
addres_space needs a VM pressure/flush callback
per file_op rw_kiovec
enhanced disk statistics
AFFS fixups
UMSDOS fixups resync
 
Drivers In 2.2 not 2.4
----------------------
Lan Media WAN
 
To Check
--------
Truncate races (Debian apt shows it nicely) [done ? - all but Coda]
Elevator and block handling queue change errors are all sorted
Check O_APPEND atomicity bug fixing is complete
Make sure all drivers return 1 from their __setup functions
Protection on isize  (sct) [Al Viro mostly done]
Mikulas claims we need to fix the getblk/mark_buffer_uptodate thing for
        2.3.x as well
Network block device seems broken by block device changes
Fbcon races
Fix all remaining PCI code to use new resources and enable_Device
VFS?VM - mmap/write deadlock
rw sempahores on page faults (mmap_sem)
kiobuf seperate lock functions/bounce/page_address fixes
Fix routing by fwmark
Some FB drivers check the A000 area and find it busy then bomb out
rw semaphores on inodes to fix read/truncate races ? [Probably fixed]
Not all device drivers are safe now the write inode lock isnt taken on write
File locking needs checking for races
Multiwrite IDE breaks on a disk error
AFFS doesn't work on current page cache
ACPI/APM suspend issue
