Subject: Build failure on latest powerpc/merge (311ae9e159d8 io_uring: fix dead-hung for non-iter fixed rw)
Date: Fri, 29 Nov 2019 14:53:10 +0000 [thread overview]
Message-ID: <71cf82d5-5986-43b7-cf1c-acba429a89d6@c-s.fr> (raw)
CC fs/io_uring.o
fs/io_uring.c: In function ‘loop_rw_iter’:
fs/io_uring.c:1628:21: error: implicit declaration of function ‘kmap’
[-Werror=implicit-function-declaration]
iovec.iov_base = kmap(iter->bvec->bv_page)
^
fs/io_uring.c:1628:19: warning: assignment makes pointer from integer
without a cast [-Wint-conversion]
iovec.iov_base = kmap(iter->bvec->bv_page)
^
fs/io_uring.c:1643:4: error: implicit declaration of function ‘kunmap’
[-Werror=implicit-function-declaration]
kunmap(iter->bvec->bv_page);
^
Reverting commit 311ae9e159d8 ("io_uring: fix dead-hung for non-iter
fixed rw") clears the failure.
Most likely an #include is missing.
