HI,

Can anyone let me know where the funtions are declared or defined,
such as btrfs_header_nritems(), btrfs_header_level(), etc? thanks.

  ctree.h, somewhere around or after line 1550. They're all accessor
functions, defined by a set of macros. Look for the *_SETGET_* macros.
The actual definitions of BTRFS_SETGET_FUNCS are in struct-funcs.h

Great, thanks.

  Hugo.
