afs: Fix error propagation from server record check/update
afs_check/update_server_record() should be setting fc->error rather than fc->ac.error as they're called from within the cursor iteration function. afs_fs_cursor::error is where the error code of the attempt to call the operation on multiple servers is integrated and is the final result, whereas afs_addr_cursor::error is used to hold the error from individual iterations of the call loop. (Note there's also an afs_vl_cursor which also wraps afs_addr_cursor for accessing VL servers rather than file servers). Fix this by setting fc->error in the afs_check/update_server_record() so that any error incurred whilst talking to the VL server correctly propagates to the final result. This results in: kAFS: Unexpected error from FS.StoreData -512 being seen, even though the store-data op is non-interruptible. The error is actually coming from the server record update getting interrupted. Fixes: d2ddc776a458 ("afs: Overhaul volume and server record caching and fileserver rotation") Signed-off-by: David Howells <dhowells@redhat.com>
