6.6.30-rc1 has a large set of fs/smb (cifs.ko and ksmbd.ko) patches backported but was missing more than 30 fixes so I put together a safe backport of the remaining, leaving out patches that had dependencies on things outside of fs/smb

The following changes since commit 488f7008e62890fae8c7a2d3583913c8074f1fc6:

smb3: fix lock ordering potential deadlock in cifs_sync_mid_result (2024-04-30 12:30:53 -0500)

smb: smb2pdu.h: Avoid -Wflex-array-member-not-at-end warnings (2024-05-01 02:18:25 -0500)

---------------------------------------------------------------- full backport for 6.6.30, includes all 80 (of the relevant) missing fs/smb changesets

Test results look good (and better than without the patches). Here are the functional test results (they passed exhaustive set of tests to various server types): http://smb311-linux-testing.southcentralus.cloudapp.azure.com/#/builders/3/b... http://smb311-linux-testing.southcentralus.cloudapp.azure.com/#/builders/5/b... http://smb311-linux-testing.southcentralus.cloudapp.azure.com/#/builders/9/b... http://smb311-linux-testing.southcentralus.cloudapp.azure.com/#/builders/10/...

Note that 22 patches had dependencies and were not appropriate to backport and are not included, but here is the list of the additional 80 fs/smb patches included, many of which fix bugs (the others reduce risk of backport, and help avoid merge conflicts): 411b6f385ac2 (HEAD -> fs-smb-backport-linux-6.6.30-rc1, tag: 6.6.30-rc1-full-fs-smb-backport, origin/fs-smb-backport-linux-6.6.30-rc1) smb:
