Package: jdupes Version: 1.21.0-1 Severity: normal Dear Maintainer, When running jdupes -rB ./ in a folder on a BTRFS filesystem, I got errors for every file: eg, [SRC] ./.git/logs/HEAD -XX-> ./.git/logs/refs/heads/master error: Inappropriate ioctl for device (25)
I have been running jdupes -B fairly regularly on various files on my device; the problems have only started now, after the most recent update of jdupes. I'm wondering if the kernel API for file deduplication changed, or strace says this is the called ioctl: ioctl(3, _IOC(_IOC_READ|_IOC_WRITE, 0x5e, 0x36, 0x18), 0x55732fa9b4e0) = -1 ENOTTY (Inappropriate ioctl for device) The bug is in upstream: in commit 0027bb2c8, the new static header incorrectly states the literal: it transforms BTRFS_IOCTL_MAGIC from the hexadecimal 0x94 (decimal 148) to the decimal 94 This is problematic: the patch is fairly trivial (add 0x to line 23 of linux-dedupe-static.h). I do wonder why the static header is used, rather than the proper kernel headers. I'll also put this bug upstream, filing it here because I started the report before I finished poking around it's cause. Thanks!
