As bitops can only operate on long objects, and
cifs_ses_get_chan_index() already returns "unsigned long", fix this by
changing cifs_ses.chans_need_reconnect and chan_index from "size_t" to
"unsigned long".

I could not find this patch in the lore archives of linux-cifs or

Are you referring to this PR?

https://github.com/sprasad-microsoft/smb-kernel-client/commit/09d387ff8f064f4d1e7e8d15b248742bac9e12aa.patch
This patch is now using chans_need_reconnect as unsigned long instead of size_t
+ /*
+ * chans_need_reconnect is a bitmap indicating which of the channels
+ * under this smb session needs to be reconnected.
+ * If not multichannel session, only one bit will be used.

+ unsigned long chans_need_reconnect;

The commit in the PR has indeed been updated, but the link[3] in the
pull request hasn't.
This makes it very difficult to find and track patches, and review
commits hidden in pull requests that don't even contain the subjects
of the patches in the pull summary. so searching in lore doesn't
find them.
The Linux review policy requires _patches_ to be sent to public
mailing lists.
Thanks for your cooperation!
