Example usage for 10 second delay:

This patch removes the arbitrary limit of 32 acl entries on ext[23] when
writing acls.  A patch that removes the same check when reding acls is in
BK since 12 March 2004, so all kernels since then are already able to read
large acls.  I think that ten+ months are enough so that we can now also
remove the write limit.

This is the read-limit patch:
http://linux.bkbits.net:8080/linux-2.6/cset%404051e2863UsuQEgAQShmimgBooAXkg?nav=index.html

Even without this patch the xattr block could already contain less space
than needed for the acl, because other attributes might already use up
almost all space.  So this patch does not introduce additional error
conditions.  We have been shipping with this patch the last year (almost).

When a new inode is created, ext3_new_inode sets the EXT3_STATE_NEW flag,
which tells ext3_do_update_inode to zero out the inode before filling in
the inode's data.  When a file is created in a directory with a default
acl, the new inode inherits the directory's default acl; this generates
attributes.  The attributes are created before ext3_do_update_inode is
called to write out the inode.  In case of in-inode attributes, the new
inode's attributes are written, and then zeroed out again by
ext3_do_update_inode.  Bad thing.

Fix this by recognizing the EXT3_STATE_NEW case in ext3_xattr_set_handle,
and zeroing out the inode there already when necessary.

When creating a filesystem with inodes bigger than 128 bytes, mke2fs fails
to clear out bytes beyond EXT3_GOOD_OLD_INODE_SIZE in all inodes it creates
(the journal, the filesystem root, and lost+found).  We would require a
zeroed-out i_extra_isize field but we don't get it, so disallow in-inode
attributes for those inodes.

We are checking for (EXT3_SB(inode->i_sb)->s_inode_size <=
EXT3_GOOD_OLD_INODE_SIZE) to find out if we can set in-inode attributes;
the test fails for inodes that have been created before the ea-in-inode
patch.  Those inodes have (i_extra_isize == 0), so we end up with the
attributes overlapping the i_extra_isize field.  Checking for
(i_extra_isize == 0) instead fixes this case.

The EXT3_STATE_XATTR flag is only set if (i_extra_isize > 0) and the inodes
has in-inode attributes, so that is enough in the first two tests.

We found strange blocks layout in our mail server, after careful study, we
got the reason and tried to fix it.

On the very fist attempt to allocate a block to the newly-initialised inode,
if we are trying to add a block at logical file offset "1" then
ext2_find_goal() will incorrectly assume that this was a next_alloc_block
cache hit (because we think the previously-allocated block was at offset
zero).

Net result: why trying to extend a freshly-opened one-block file we end up
deciding to place the second file block at disk block "1", rather than going
off and calling ext2_find_near().

Fix it by checking that we actually do have something valid cached in
next_alloc_goal.

Andi Kleen reported a problem where a very slow boot caused the timer
interrupt on a secondary CPU to go off before the CPU was actually brought
up by the core code, so the CPU_PREPARE notifier hadn't been called, so the
per-cpu timer code wasn't set up.

This was caused by enabling interrupts around calibrate_delay() on
secondary CPUs, which is not actually neccessary (interrupts on CPU 0
increments jiffies, which is all that is required).  So delay enabling
interrupts until the actual __cpu_up() call for that CPU.

This patch is from Nathan Lynch <nathanl@austin.ibm.com>.

This changes struct device_node and associated code to use the kref api for
object refcounting and freeing.  I've given it some testing on pSeries with
cpu add/remove and verified that the release function works.  The change is
somewhat cosmetic but it does make the code easier to understand...  at least
I think so =)

The only real change is that the refcount on all device_nodes is initialized
at 1, and the device node is freed when the refcount reaches 0 (of_remove_node
has the extra "put" to ensure that this happens).  This lets us get rid of the
OF_STALE flag and macros in prom.h.

This patch is from Craig Chaney <cchaney@us.ibm.com>.

This patch moves the restoring of the stack pointer in the system call exit
path to after the point where we clear the RI (recoverable interrupt) bit in
the MSR.  Normally, loading the stack pointer before clearing RI doesn't cause
any problem because there is no trap that can normally occur in between.  But
if we are tracing the code using a tool that single-steps instructions, this
can cause a problem.  In this case, clearing RI serves as an indication that
the following code can't be safely single-stepped.
