| |
Hi all,
After merging the vfs tree, today's linux-next build (arm multi_v7_defconfig) failed like this:
fs/eventfd.c: In function 'eventfd_read': fs/eventfd.c:226:6: error: implicit declaration of function 'iov_iter_count' [-Werror=implicit-function-declaration] 226 | if (iov_iter_count(to) < sizeof(ucnt)) | ^~~~~~~~~~~~~~ In file included from include/linux/file.h:9, from fs/eventfd.c:9: fs/eventfd.c:257:15: error: implicit declaration of function 'copy_to_iter'; did you mean 'copy_to_user'? [-Werror=implicit-function-declaration] 257 | if (unlikely(copy_to_iter(&ucnt, sizeof(ucnt), to) != sizeof(ucnt))) | ^~~~~~~~~~~~
Caused by commit
a6515b3a7410 ("eventfd: convert to f_op->read_iter()")
I have applied the following patch for today:
