So far I can tell, the regression is in 6.1.y only and might indicate that some prerequisite changes (maybe in the folio refactoring?) is missing. The commit identified by Suraj, 7b2404a886f8 ("cifs: Fix flushing, invalidation and file size with copy_file_range()") from 6.7-rc5 was backported to two of the stable series, 6.1.68 and 6.6.7. I did not test mainline specifically (would need to first build) but did test 6.6.9 based version and the problem is not reproduible there (and neither with 6.6.10-rc1 which I have build for the RC series review posting). For this reason I added to regzbot only "regzbot ^introduced 18b02e4343e8f5be6a2f44c7ad9899b385a92730" which is the commit in v6.1.68. Regards, Salvatore
