[LSF/MM ATTEND] File system and storage topics

[LSF/MM ATTEND] File system and storage topics

[Anton Altaparmakov]

Hi,

I am the NTFS file system maintainer in the kernel (have been for the last 15 years) and am the file system development lead for Tuxera Inc. (I wrote the Tuxera NTFS, FAT, and exFAT kernel drivers) and have extensive experience in all power/fail safety, self healing and performance aspects of file systems and storage.  Perhaps less relevant, but I also wrote the NTFS driver in Mac OS X so I have experience of the xnu kernel as well.

I am interested in attending LSF/MM to discuss power/fail safe testing/issues, resilience/self healing, SMR drives, AIO, persistent memory, O_ATOMIC, performance and general file system and storage discussions.

Whilst I will also be attending Vault I feel that attending LSF/MM will be of benefit as it will allow more face to face discussions with other core kernel developers.

Thanks a lot in advance you for your consideration.

Best regards,

	Anton

There are also a set of issues around whether and how
to expose certain NTFS-like/Windows-like/SMB-like
metadata to user space (not just the RichACL discussion
but also some of the special inode types, including
a variety of useful types of reparse points)
that I would be interested in discussing.

Hmmm. If you're going to be discussing this,
then I'd probably like to be there also (I'm
going to Boston for Vault also, so I'll be
around).

Yes, that would be good.  Currently we have a horrible mess from not exposed at all over to exposed by different API such as xattr and ioctl and each different for each file system.  Both us and userspace would benefit if we had some consistency.

I have not been invited to LSF/MM (or at least not yet) but I will be at Vault so we can hopefully meet up there...

Best regards,
