I am looking at something like this to implement read-only for those inodes:
Yikes. Treating individual inodes in a file systems as read-only
is about the most confusing and harmful behavior we could do.
That was the suggestion which I was given earlier in this thread.
Just treat it as any other rocompat feature please an mount the entire
file system read-only if not supported.
Or even better let this wait a little, and work with Darrick to work
on the rextsize > 1 reflіnk patches and just make the thing work.
I'll let Darrick comment on this.
So what about forcealign and RT?
Any opinion on this?
What about forcealign and RT?
In this series version I was mounting the whole FS as RO if
XFS_FEAT_FORCEALIGN and XFS_FEAT_REFLINK was found in the SB. And so
very different to how I was going to individual treat inodes which
happen to be forcealign and reflink, above.
So I was asking guidance when whether that approach (for RT and
forcealign) is sound.
