__getblk() adds __GFP_NOFAIL, which is unnecessary for readahead; we're quite comfortable with the possibility that we may not get a bh back. Switch to bdev_getblk() which does not include __GFP_NOFAIL. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> --- fs/buffer.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-)
