[gentoo-user] gentoo-sources-6.7.7 build error

[ralfconn]

I have a build error with latest gentoo-sources (~amd64): # eix -I 
gentoo-sources Installed versions: 6.7.6(6.7.6)^bs(10:37:31 
02/24/24)(-build -experimental -symlink) 6.7.7(6.7.7)^bs(18:43:20 
03/01/24)(-build -experimental -symlink) # eix -I gcc Installed 
versions: 13.2.1_p20240210(13)^t(17:09:30 02/18/24)(cet cxx 
default-stack-clash-protection default-znow fortran hardened nls openmp 
pie sanitize ssp -ada -custom-cflags -d -debug -doc -fixed-point -go

[-Werror=unused-variable]  2460 |         loff_t i_size = 
i_size_read(&ni->vfs_inode);

This is on a gentoo box with mixed profile 
(local:no-multilib-hardened-desktop (dev)). The vanilla kernel 
downloaded from kernel.org - with same config - has the same build 
error. I thought it could be a hardened-related issue, but a different 
gentoo box with an hardened-dektop profile builds fine. The kernel 
config is different, though. By the way, looking at the failing source 
it seems to me that the error is a false positive. I suppose nobody else 
is seeing this, I see no reports on the net. Any hints? Should I file a 
bug upstream? thanks, raffaele

Already known:
https://lore.kernel.org/stable/2024030214-scratch-compactly-638f@gregkh/

So either set CONFIG_NTFS3_LZX_XPRESS=y or just wait.

-h

Wow, faster than light, thanks!

In addition to the suggested fix, also disabling NTFS support completely 
works.

thanks again,
