Kuniyuki Iwashima dba5c748c9 nfsd: Don't call freezable_schedule_timeout() after each successful page allocation in svc_alloc_arg(). ... When commit 390390240145 ("nfsd: don't allow nfsd threads to be signalled.") is backported to 5.10, it was adjusted considering commit 3feac2b55293 ("sunrpc: exclude from freezer when waiting for requests:"). However, 3feac2b55293 is based on commit f6e70aab9dfe ("SUNRPC: refresh rq_pages using a bulk page allocator"), which converted page-by-page allocation to a batch allocation, so schedule_timeout() is placed un-nested. As a result, the backported commit 7229200f6866 ("nfsd: don't allow nfsd threads to be signalled.") placed freezable_schedule_timeout() in the wrong place. Now, freezable_schedule_timeout() is called after every successful page allocation, and we see 30%+ performance regression on 5.10.220 in our test suite. Let's move it to the correct place so that freezable_schedule_timeout() is called only when page allocation fails. Fixes: 7229200f6866 ("nfsd: don't allow nfsd threads to be signalled.")
