Hi Benjamin, After merging the aio tree, today's linux-next build (powerpc ppc64_defconfig) failed like this:
In file included from include/linux/kernel.h:13:0,
from fs/aio.c:13:
fs/aio.c: In function 'aio_free_ring':
fs/aio.c:188:32: error: 'struct dentry' has no member named 'd_count'
aio_ring_file->f_path.dentry->d_count,
^
include/linux/printk.h:246:38: note: in definition of macro 'pr_debug'
no_printk(KERN_DEBUG pr_fmt(fmt), ##__VA_ARGS__)
^
Caused by commit 36bc08cc0170 ("s/aio: Add support to aio ring pages
migration") interacting with commit 98474236f72e ("vfs: make the dentry
cache use the lockref infrastructure") from Linus' tree.
I applied the following (probably suboptimal) fix and can carry it as
necessary.
