           Summary: Dolphin emits a system log message for every file
                    moved across file systems
    Classification: Applications
           Product: dolphin
           Version: 24.12.1

dolphin file operation logged in system log

SUMMARY

For every file copied or moved across a file system border (tested here with
btrfs from/to xfs or btrfs subvolume to btrfs subvolume) a message is created
in the system log including the full transactions paths.

STEPS TO REPRODUCE

1. E.g. on btrfs create a subvolume A and a subvolume B
2. Touch a new file on subvolumeA
2. Move that file from subvolume A to subvolume B

OBSERVED RESULT

A log entry is generated:  dolphin[]: kf.kio.workers.file: copy() QUrl("<source
parh>) to QUrl("<target path>") mode= 420

EXPECTED RESULT

Dolphin should not emit a message for every copied file. 

Copying a lot of files in 100+ or worst case 10k+ range completely floods the
system log making it very hard to use.

While rather abstract there is an argument leaking meta information. E.g. a
user can move a file to the trash and delete it, but on btrfs this still move
the file across subvolumes logging it.
