Hi,

The following patchset contains Netfilter fixes for net:

Patch #1 unlike early commit path stage which triggers a call to abort,
         an explicit release of the batch is required on abort, otherwise
         mutex is released and commit_list remains in place.

Patch #2 release mutex after nft_gc_seq_end() in commit path, otherwise
         async GC worker could collect expired objects.

Patch #3 flush pending destroy work in module removal path, otherwise UaF
         is possible.

Patch #4 and #6 restrict the table dormant flag with basechain updates
	 to fix state inconsistency in the hook registration.

Patch #5 adds missing RCU read side lock to flowtable type to avoid races
	 with module removal.

Please, pull these changes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf.git nf-24-04-04

Thanks.
