[PATCH RESEND 00/11] cifs: Various changes

[Pali Rohár]

This patch series contains various cifs changes which I sent year ago.
All those patches are rebased on top of the 7.2-rc2 and there is no new
change in them, just they are rebased for new code base.

I pushed these changes also into my git branch cifs:
https://git.kernel.org/pub/scm/linux/kernel/git/pali/linux.git/log/?h=cifs


Note that patch "cifs: Remove cifs_backup_query_path_info() and replace
it by cifs_query_path_info()" is removing these lines:

-			move_cifs_info_to_smb2(&data->fi, fi);
-			fdi = (FILE_DIRECTORY_INFO *)fi;
-			si = (FILE_ID_FULL_DIR_INFO *)fi;

And I have feeling that in this old code (which is being) removed could
be a buffer overflow as it is casting between incompatible structures.
I have not spent too much time with it as the code is begin removed.
But maybe some AI tool could be able to confirm if this is some buffer
overflow or not.
