Merge tag 'vfs-7.0-rc2.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs fixes from Christian Brauner:

 - Fix an uninitialized variable in file_getattr().

   The flags_valid field wasn't initialized before calling
   vfs_fileattr_get(), triggering KMSAN uninit-value reports in fuse

 - Fix writeback wakeup and logging timeouts when DETECT_HUNG_TASK is
   not enabled.

   sysctl_hung_task_timeout_secs is 0 in that case causing spurious
   "waiting for writeback completion for more than 1 seconds" warnings

 - Fix a null-ptr-deref in do_statmount() when the mount is internal

 - Add missing kernel-doc description for the @private parameter in
   iomap_readahead()

 - Fix mount namespace creation to hold namespace_sem across the mount
   copy in create_new_namespace().

   The previous drop-and-reacquire pattern was fragile and failed to
   clean up mount propagation links if the real rootfs was a shared or
   dependent mount

 - Fix /proc mount iteration where m->index wasn't updated when
   m->show() overflows, causing a restart to repeatedly show the same
   mount entry in a rapidly expanding mount table

 - Return EFSCORRUPTED instead of ENOSPC in minix_new_inode() when the
   inode number is out of range

 - Fix unshare(2) when CLONE_NEWNS is set and current->fs isn't shared.

   copy_mnt_ns() received the live fs_struct so if a subsequent
   namespace creation failed the rollback would leave pwd and root
   pointing to detached mounts. Always allocate a new fs_struct when
   CLONE_NEWNS is requested

 - fserror bug fixes:

    - Remove the unused fsnotify_sb_error() helper now that all callers
      have been converted to fserror_report_metadata

    - Fix a lockdep splat in fserror_report() where igrab() takes
      inode::i_lock which can be held in IRQ context.

      Replace igrab() with a direct i_count bump since filesystems
      should not report inodes that are about to be freed or not yet
      exposed

 - Handle error pointer in procfs for try_lookup_noperm()

 - Fix an integer overflow in ep_loop_check_proc() where recursive calls
   returning INT_MAX would overflow when +1 is added, breaking the
   recursion depth check

 - Fix a misleading break in pidfs
