This allow us to print out fsnotify details such as watchee inode, device, mask and optionally a file handle. For inotify objects if kernel compiled with exportfs support the output will be | pos: 0 | flags: 02000000 | inotify wd:3 ino:9e7e sdev:800013 mask:800afce ignored_mask:0 fhandle-bytes:8 fhandle-type:1 f_handle:7e9e0000640d1b6d | inotify wd:2 ino:a111 sdev:800013 mask:800afce ignored_mask:0 fhandle-bytes:8 fhandle-type:1 f_handle:11a1000020542153 | inotify wd:1 ino:6b149 sdev:800013 mask:800afce ignored_mask:0 fhandle-bytes:8 fhandle-type:1 f_handle:49b1060023552153 If kernel compiled without exportfs support, the file handle won't be provided but inode and device only. | pos: 0 | flags: 02000000 | inotify wd:3 ino:9e7e sdev:800013 mask:800afce ignored_mask:0 | inotify wd:2 ino:a111 sdev:800013 mask:800afce ignored_mask:0 | inotify wd:1 ino:6b149 sdev:800013 mask:800afce ignored_mask:0 For fanotify the output is like | pos: 0 | flags: 04002 | fanotify flags:10 event-flags:0 | fanotify mnt_id:12 mask:3b ignored_mask:0 | fanotify ino:50205 sdev:800013 mask:3b ignored_mask:40000000 fhandle-bytes:8 fhandle-type:1 f_handle:05020500fb1d47e7 To minimize impact on general fsnotify code the new functionality is gathered in fs/notify/fdinfo.c file.
