      tpm: Allow system suspend to continue when TPM suspend fails · 1382999a
      Jason A. Donenfeld authored
      TPM 1 is sometimes broken across system suspends, due to races or
      locking issues or something else that haven't been diagnosed or fixed
      yet, most likely having to do with concurrent reads from the TPM's
      hardware random number generator driver. These issues prevent the system
      from actually suspending, with errors like:
      
        tpm tpm0: A TPM error (28) occurred continue selftest
        ...
        tpm tpm0: A TPM error (28) occurred attempting get random
        ...
        tpm tpm0: Error (28) sending savestate before suspend
        tpm_tis 00:08: PM: __pnp_bus_suspend(): tpm_pm_suspend+0x0/0x80 returns 28
        tpm_tis 00:08: PM: dpm_run_callback(): pnp_bus_suspend+0x0/0x10 returns 28
        tpm_tis 00:08: PM: failed to suspend: error 28
        PM: Some devices failed to suspend, or early wake event detected
      
      This issue was partially fixed by 23393c64 ("char: tpm: Protect
      tpm_pm_suspend with locks"), in a last minute 6.1 commit that Linus took
      directly because the TPM maintainers weren't available. However, it
      seems like this just addresses the most common cases of the bug, rather
      than addressing it entirely. So there are more things to fix still,
      apparently.
      
      In lieu of actually fixing the underlying bug, just allow system suspend
      to continue, so that laptops still go to sleep fine. Later, this can be
      reverted when the real bug is fixed.

      hfs/hfsplus: avoid WARN_ON() for sanity check, use proper error handling · cb7a95af
      Linus Torvalds authored
      Commit 55d1cbbb ("hfs/hfsplus: use WARN_ON for sanity check") fixed
      a build warning by turning a comment into a WARN_ON(), but it turns out
      that syzbot then complains because it can trigger said warning with a
      corrupted hfs image.
      
      The warning actually does warn about a bad situation, but we are much
      better off just handling it as the error it is.  So rather than warn
      about us doing bad things, stop doing the bad things and return -EIO.
      
      While at it, also fix a memory leak that was introduced by an earlier
      fix for a similar syzbot warning situation, and add a check for one case
      that historically wasn't handled at all (ie neither comment nor
      subsequent WARN_ON).

      Pull block fixes from Jens Axboe:
       "The big change here is obviously the revert of the pktcdvd driver
        removal. Outside of that, just minor tweaks. In detail:
      
         - Re-instate the pktcdvd driver, which necessitates adding back
           bio_copy_data_iter() and the fops->devnode() hook for now (me)
      
         - Fix for splitting of a bio marked as NOWAIT, causing either nowait
           reads or writes to error with EAGAIN even if parts of the IO
           completed (me)
      
         - Fix for ublk, punting management commands to io-wq as they can all
           easily block for extended periods of time (Ming)
      
         - Removal of SRCU dependency for the block layer (Paul)"
