Subject: linux-next: manual merge of the vfs tree with the syscalls tree
Hi Al,
Today's linux-next merge of the vfs tree got a conflict in:
arch/sparc/kernel/sys_sparc32.c
between commits:
4b5d3cc0fff9 ("fs: add ksys_ftruncate() wrapper; remove in-kernel calls to sys_ftruncate()")
316dd9ee7b15 ("fs: add ksys_sync_file_range helper(); remove in-kernel calls to syscall")
eb16d89821c8 ("fs: add ksys_truncate() wrapper; remove in-kernel calls to sys_truncate()")
cdf490758828 ("fs: add ksys_p{read,write}64() helpers; remove in-kernel calls to syscalls")
757df4a44629 ("fs: add ksys_fallocate() wrapper; remove in-kernel calls to sys_fallocate()")
50811e2580e0 ("mm: add ksys_fadvise64_64() helper; remove in-kernel call to sys_fadvise64_64()")
c008a19d1399 ("mm: add ksys_readahead() helper; remove in-kernel calls to sys_readahead()")
from the syscalls tree and commit:
a00a700bdea8 ("sparc: get rid of remaining SIGN... wrappers")
8ccb004677d1 ("convert compat sync_file_range() to COMPAT_SYSCALL_DEFINE")
8c82ccd63192 ("sparc: switch compat pread64 and pwrite64 to COMPAT_SYSCALL_DEFINE")
3d0e354e4e51 ("sparc: switch compat {f,}truncate64() to COMPAT_SYSCALL_DEFINE")
from the vfs tree.
I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
