Kernel 3.x patches with EL7 issues

Resolved. Mainline kernel's (4.9 and later) freevxfs and HP-UX 11 vxfs rev 4 image seem to work

Glad to see it works, it seems we have done it. yes, you are right about 4.18. These changes have been merged into mainline since 4.9 kernel. CentOS/Rhel7 - good enough, I don't miss it. I was thinking that loop device may require to set block size up explicitly for this kernel otherwise a change requested by the module on-the-fly fails. It's just a guess so I can be wrong. You are welcome and I'm glad too we have done good job on this. I'm going to close the ticket on Friday. It will have resolved...

Sure, I don't like to give up for poor or no reason. Splendid. So, let me share my conclusion. Well, I mounted the p20M.vxfs and also the very 1st one 100M image successfully. Double checked cksums of files and all remained intact. Please see attached test script and screenshot for reference. I worked on 4.4 kernel with backported vxfs module. I had to use sort before calling final cksum on cksums because Linux bash and HP-UX use slightly different file sorting order by default. I must admit that...

You are welcome. That's interesting because I used to develop scsi tape drive emulations years ago. So you want to have this solved likely and it seems you can create vxfs image with ease. That is good idea on creating some test image however if you create more test images then these images may help sorting this out better. It is not about image size but rather diversity and let's have this done: image #1 : empty 10MB image #2 : empty 20MB image #3 : 10MB with one file of a few kB size (whatever...

It is sad to hear that your effort was wasted. I will describe background of this kernel module more detailed. Me and maybe w few others in the World use this facility to maintain user file system created by logic analyzer tool which runs hp ux 10. (see ref. https://www.techtravels.org/2020/03/mount_hpux_in_linux/) If there are any changes to SB layout in hp ux 11 then adding support for them in the kernel module will require further reverse engineering and working on raw fs images. Unfortunately...

Reworked code to be more compatible with Debian-based OS's
