Subject: linux-next: build failure after merge of the vfs-brauner tree
Date: Wed, 21 May 2025 20:49:23 +1000 [thread overview]
Message-ID: <20250521204923.1e002f04@canb.auug.org.au> (raw)
[-- Attachment #1: Type: text/plain, Size: 1803 bytes --]
Hi all,
After merging the vfs-brauner tree, today's linux-next build (x86_84
allnoconfig) failed like this:
x86_64-linux-gnu-ld: fs/coredump.o: in function `do_coredump':
coredump.c:(.text+0x1795): undefined reference to `sock_from_file'
x86_64-linux-gnu-ld: coredump.c:(.text+0x17a6): undefined reference to `sock_from_file'
x86_64-linux-gnu-ld: coredump.c:(.text+0x17b3): undefined reference to `kernel_sock_shutdown'
Caused by commit
997e88a74ed6 ("coredump: add coredump socket")
# CONFIG_NET is not set
I have applied the following hack for today to make it build.
