Revision 64165b1affc5bc16231ac971e66aae7d68d57f2c authored by Hugh Dickins on 19 April 2019, 00:50:09 UTC, committed by Linus Torvalds on 19 April 2019, 16:46:04 UTC
The old try_to_unuse() implementation was driven by find_next_to_unuse(),
which terminated as soon as all the swap had been freed.
Add inuse_pages checks now (alongside signal_pending()) to stop scanning
mms and swap_map once finished.
The same ought to be done in shmem_unuse() too, but never was before,
and needs a different interface: so leave it as is for now.
