6.15.5 stable request, regression from 6.15.3..6.15.4

Hi,

Details in the patch attached, but an unrelated vfs change broke io_uring for anon inode reading/writing. Please queue this up asap for 6.15.5 so we don't have have any further 6.15-stable kernels with this regression.

You can also just cherry pick it, picks cleanly. Sha is:
