[PATCH v2 000/110] vfs: change inode->i_ino from unsigned long to u64

by Jeff Layton

This version splits the change up to be more bisectable. It first adds a new kino_t typedef and a new "PRIino" macro to hold the width specifier for format strings. The conversion is done, and then everything is changed to remove the new macro and typedef. I also missed a few places in the earlier set. This one hopefully does a bit more thorough job. My thanks and apologies to everyone who sent R-b/A-b for the v1 series. v2 breaks a lot of the changes up into two patches so many of those didn't carry over. Please resend those if you're still OK with it. The entire pile is in the "iino-u64" branch of my tree, if anyone is interested in testing this: https://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux.git/ Original cover letter follows: ----------------------8<----------------------- Christian said [1] to "just do it" when I proposed this, so here we are! For historical reasons, the inode->i_ino field is an unsigned long, which means that it's 32 bits on 32 bit architectures. This has caused a number of filesystems to implement hacks to hash a 64-bit identifier into a 32-bit field, and deprives us of a universal identifier field for an inode. This patchset changes the inode->i_ino field from an unsigned long to a u64. This shouldn't make any material difference on 64-bit hosts, but 32-bit hosts will see struct inode grow by at least 4 bytes. This could have effects on slabcache sizes and field alignment. The bulk of the changes are to format strings and tracepoints, since the kernel itself doesn't care that much about the i_ino field. The first patch changes some vfs function arguments, so check that one out carefully. With this change, we may be able to shrink some inode structures. For instance, struct nfs_inode has a fileid field that holds the 64-bit inode number. With this set of changes, that field could be eliminated. I'd rather leave that sort of cleanups for later just to keep this simple. Much of this set was generated by LLM, but I attributed it to myself since I consider this to be in the "menial tasks" category of LLM usage.

Forgot Your Crypto Wallet Password? Here's What to Do

by hamtonbecky＠gmail.com

Forgetting the password to your crypto wallet can be incredibly stressful, especially with valuable assets at stake. Unlike traditional accounts, most non-custodial crypto wallets (like MetaMask, Exodus, Electrum, or hardware wallets) don't offer simple "forgot password" resets. Recovery depends entirely on your wallet type and backups. Key Recovery Options If You Have Your Recovery Phrase (Seed Phrase) This is the most reliable method. Most wallets use a 12- or 24-word recovery phrase to restore access. Uninstall/reinstall the wallet app or extension. Choose "Import" or "Recover" wallet. Enter your seed phrase. Set a new password. This works for wallets like Crypto.com, Bitcoin.com, and many others. Always store your seed phrase securely offline. For Custodial Wallets/Exchanges If your funds are on a platform like Blockchain.com (trading account) or an exchange, use their official "Forgot Password" feature. Enter your email/phone, verify identity, and reset via link or support. These are easier since the platform holds keys. Try Remembering or Brute-Forcing (Limited Success) Brainstorm variations based on hints, patterns, or old passwords. For some wallets (e.g., Bitcoin Core .dat files), advanced users try tools like Hashcat or John the Ripper on their own hardware. This is time-consuming, technical, and often unsuccessful for strong passwords. If Nothing Works Without the seed phrase or backups, self-recovery is usually impossible due to crypto's strong security design. Many users permanently lose access. If you need expert help, reach out to Cryptera Chain Signals (CCS), a specialized firm in crypto fund recovery and wallet restoration. They assist with inaccessible wallets and related issues using advanced forensics and tracing. Website: https://www.crypterachainsignals.com/ Email: info(a)crypterachainsignals.com Important Warnings Never share your seed phrase, private keys, or password with anyone. Beware of scams promising guaranteed recovery for upfront fees. Prevention is key: Back up your seed phrase securely and use strong, memorable passwords. Act quickly and carefully your funds depend on it. Good luck!

[PATCH 0/9] accel: New driver for NXP's Neutron NPU

by Ioana Ciocoi-Radulescu

Introduce a new accel driver for the Neutron Neural Processing Unit (NPU), along with associated dt-bindings and DTS node. The first patch extends the GEM DMA helper APIs to allow bidirectional mapping of non-coherent DMA buffers. While not part of the Neutron driver, it's a prerequisite allowing us to use the GEM DMA helper. Neutron is a Neural Processing Unit from NXP, providing machine learning (ML) acceleration for edge AI applications. Neutron is integrated on NXP SoCs such as the i.MX95. The NPU consists of the following: - RISC-V core running a proprietary firmware - One or more Neutron cores, representing the main computation engine performing ML operations - Dedicated fast memory (TCM) - DMA engine that handles data transfers between DDR and TCM The firmware is closed source and distributed as a binary here [1]. The Neutron software stack also contains a userspace library [1] and a LiteRT custom delegate [2] that allow integration with standard LiteRT tools.
