Yet another ceph+fscrypt posting. The main changes since v13: - rebased onto v5.18-rc4 + ceph testing branch patches, fixed up minor merge conflicts, and squashed a few patches together - squashed in a number of patches from Xiubo to fix issues with truncation handling - incorporated Luís' patches to encrypt snapshot names - dropped a patch to export fscrypt's base64 implementation, since Luís' snapshot implementation added a new variant that we need to use. At this point, I'm mainly waiting on Al to merge this patch into -next and eventually into v5.19: fs: change test in inode_insert5 for adding to the sb list Once that's in, it should clear the way for us to start merging the rest of the pile (though probably not all at once). There are also some mysterious failures that have cropped up in testing with teuthology, particularly with thrash testing. We'll need to get to the bottom of that before we can merge the bulk of these patches. I've updated the wip-fscrypt branch in the ceph tree with this pile for now. Help with testing would be welcome!
