but it is used for N < M case only. We want to use it for any case.
By this patch, not only N:M connection, but all existing connection
(1:1, 1:N, N:N) will use same connection mapping. Then, because it will
use default mapping, no conversion patch is needed to exising drivers.
More over, CPU:Codec = N:M (N > M) also supported in the same time.

- With the usage of simple_recursive_remove() recommended by Al Viro,
the code should not be calling "d_invalidate()" itself. Doing so
is causing crashes. The code was calling d_invalidate() on the race
of trying to look up a file while the parent was being deleted.
This was detected, and the added dentry was having d_invalidate() called
on it, but the deletion of the directory was also calling d_invalidate()
on that same dentry.
- A fix to not free the eventfs_inode (ei) until the last dput() was called
on its ei->dentry made the ei->dentry exist even after it was marked
for free by setting the ei->is_freed. But code elsewhere still was
checking if ei->dentry was NULL if ei->is_freed is set and would
trigger WARN_ON if that was the case. That's no longer true and there
should not be any warnings when it is true.
- Use GFP_NOFS for allocations done under eventfs_mutex.
The eventfs_mutex can be taken on file system reclaim, make sure
that allocations done under that mutex do not trigger file system
reclaim.
- Clean up code by moving the taking of inode_lock out of the helper
functions and into where they are needed, and not use the
parameter to know to take it or not. It must always be held but
some callers of the helper function have it taken when they were
called.
- Warn if the inode_lock is not held in the helper functions.
- Warn if eventfs_start_creating() is called without a parent.
As eventfs is underneath tracefs, all files created will have
a parent (the top one will have a tracefs parent).
Tracing update;
- Add Mathieu Desnoyers as an official reviewer of the tracing sub system.

Pull tracing fixes from Steven Rostedt::
"Eventfs fixes:
- With the usage of simple_recursive_remove() recommended by Al Viro,
the code should not be calling "d_invalidate()" itself. Doing so is
causing crashes. The code was calling d_invalidate() on the race of
trying to look up a file while the parent was being deleted. This
was detected, and the added dentry was having d_invalidate() called
on it, but the deletion of the directory was also calling
d_invalidate() on that same dentry.
- A fix to not free the eventfs_inode (ei) until the last dput() was
called on its ei->dentry made the ei->dentry exist even after it
was marked for free by setting the ei->is_freed. But code elsewhere
still was checking if ei->dentry was NULL if ei->is_freed is set
and would trigger WARN_ON if that was the case. That's no longer
true and there should not be any warnings when it is true.
- Use GFP_NOFS for allocations done under eventfs_mutex. The
eventfs_mutex can be taken on file system reclaim, make sure that
allocations done under that mutex do not trigger file system
reclaim.
- Clean up code by moving the taking of inode_lock out of the helper
functions and into where they are needed, and not use the parameter
to know to take it or not. It must always be held but some callers
of the helper function have it taken when they were called.
- Warn if the inode_lock is not held in the helper functions.
- Warn if eventfs_start_creating() is called without a parent. As
eventfs is underneath tracefs, all files created will have a parent
(the top one will have a tracefs parent).
Tracing update:
- Add Mathieu Desnoyers as an official reviewer of the tracing subsystem"

Merge tag 'parisc-for-6.7-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc architecture fixes from Helge Deller:
"This patchset fixes and enforces correct section alignments for the
ex_table, altinstructions, parisc_unwind, jump_table and bug_table
which are created by inline assembly.
Due to not being correctly aligned at link & load time they can
trigger unnecessarily the kernel unaligned exception handler at
runtime. While at it, I switched the bug table to use relative
addresses which reduces the size of the table by half on 64-bit.
We still had the ENOSYM and EREMOTERELEASE errno symbols as left-overs
from HP-UX, which now trigger build-issues with glibc. We can simply
remove them.
Most of the patches are tagged for stable kernel series.
Summary:
- Drop HP-UX ENOSYM and EREMOTERELEASE return codes to avoid glibc
build issues
- Fix section alignments for ex_table, altinstructions, parisc unwind
table, jump_table and bug_table
- Reduce size of bug_table on 64-bit kernel by using relative
pointers"
* tag 'parisc-for-6.7-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
parisc: Reduce size of the bug_table on 64-bit kernel by half
parisc: Drop the HP-UX ENOSYM and EREMOTERELEASE error codes
parisc: Use natural CPU alignment for bug_table
parisc: Ensure 32-bit alignment on parisc unwind section
parisc: Mark lock_aligned variables 16-byte aligned on SMP
parisc: Mark jump_table naturally aligned
parisc: Mark altinstructions read-only and 32-bit aligned
parisc: Mark ex_table entries 32-bit aligned in uaccess.h
parisc: Mark ex_table entries 32-bit aligned in assembly.h

confusion when distros backport fixes.
