Tried running the regression tests against for-next and saw crash early in the test run in # FS QA Test No. cifs/006 # # check deferred closes on handles of deleted files # umount: /mnt/test: not mounted. umount: /mnt/test: not mounted. umount: /mnt/scratch: not mounted. umount: /mnt/scratch: not mounted. ./run-xfstests.sh: line 25: 4556 Segmentation fault rmmod cifs modprobe: ERROR: could not insert 'cifs': Device or resource busy More information here: http://smb311-linux-testing.southcentralus.cloudapp.azure.com/#/builders/5/builds/123/steps/14/logs/stdio Are you also seeing that? There are not many likely candidates for what patch is causing the problem (could be related to the folios changes) e.g. 7c1ac89480e8 cifs: Enable large folio support 3ee1a1fc3981 cifs: Cut over to using netfslib 69c3c023af25 cifs: Implement netfslib hooks c20c0d7325ab cifs: Make add_credits_and_wake_if() clear deducted credits edea94a69730 cifs: Add mempools for cifs_io_request and cifs_io_subrequest structs 3758c485f6c9 cifs: Set zero_point in the copy_file_range() and remap_file_range() 1a5b4edd97ce cifs: Move cifs_loose_read_iter() and cifs_file_write_iter() to file.c dc5939de82f1 cifs: Replace the writedata replay bool with a netfs sreq flag 56257334e8e0 cifs: Make wait_mtu_credits take size_t args ab58fbdeebc7 cifs: Use more fields from netfs_io_subrequest a975a2f22cdc cifs: Replace cifs_writedata with a wrapper around netfs_io_subrequest 753b67eb630d cifs: Replace cifs_readdata with a wrapper around netfs_io_subrequest 0f7c0f3f5150 cifs: Use alternative invalidation to using launder_folio 2e9d7e4b984a mm: Remove the PG_fscache alias for PG_private_2 Any ideas? -- Thanks, Steve
