This is a note to let you know that I've just added the patch titled
SUNRPC: Change return value type of .pc_encode
to the 5.15-stable tree which can be found at:
http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary
The filename of the patch is:
sunrpc-change-return-value-type-of-.pc_encode.patch
and it can be found in the queue-5.15 subdirectory.
If you, or anyone else, feels it should not be added to the stable tree,
please let <stable@xxxxxxxxxxxxxxx> know about it.
commit f900a5811c293b9fb4b0e064a46eee1002dccacf
Author: Chuck Lever <chuck.lever@xxxxxxxxxx>

SUNRPC: Change return value type of .pc_encode
[ Upstream commit 130e2054d4a652a2bd79fb1557ddcd19c053cb37 ]
Returning an undecorated integer is an age-old trope, but it's
not clear (even to previous experts in this code) that the only
valid return values are 1 and 0. These functions do not return
a negative errno, rpc_stat value, or a positive length.
Document there are only two valid return values by having
.pc_encode return only true or false.
