fs: expand dump_inode()
This adds fs name and few fields from struct inode: i_mode, i_opflags,
i_flags, i_state and i_count.
All values printed raw, no attempt to pretty-print anything.
Compile tested on i386 and runtime tested on amd64.
Sample output:
[ 23.121281] VFS_WARN_ON_INODE("crap") encountered for inode ffff9a1a83ce3660
fs pipefs mode 10600 opflags 0x4 flags 0x0 state 0x38 count 0
