I see many "Couldn't get user pages" netfs errors running cifs/102
regression test (which tests for leaked file handles) when using
current mainline from today (which includes the recent netfs read
retry fixes). For example many of:
[Mon Feb 17 14:08:31 2025] netfs: Couldn't get user pages (rc=-4)
[Mon Feb 17 14:08:31 2025] netfs: Zero-sized read [R=32f]
[Mon Feb 17 14:08:31 2025] netfs: Couldn't get user pages (rc=-4)
Anyone else see netfs problems when running with current mainline?
The test does the following (checking for handle leaks):
# Create a file to test with
echo "hello world" > $TEST_DIR/leak
# Try to kill a 'cat' when it is opening/closing a file
(for i in {1..5000} ; do cat $TEST_DIR/leak & sleep 0.0001 ; kill -9
$! ; done) >/dev/null 2>&1
sleep 3
# and verify if we have any leaked filehandles
smbstatus | grep -i Locked -A1000
