File Change Log record

An application reads the FCL file through the vxfs_fcl_read() function.

Each fcl_record structure represents a logical event recorded in the FCL. It is defined as the following:

struct fcl_record {
  uint32_t  fr_reclen;           /* Record length */
  uint16_t  fr_op;               /* Operation type. */
  uint16_t  fr_unused1;          /* unused field */
  uint32_t  fr_acsinfovalid : 1;   /* fr_acsinfo field valid */
  uint32_t  fr_newnmvalid : 1; /* fr_newfilename field is valid */
  uint32_t  fr_pinogenvalid : 1; /* fr_fr_pinogen field is valid */
  uint32_t  fr_unused2 : 29;       /* Future use */
  uint64_t  fr_inonum;           /* Inode Number. */
  uint32_t  fr_inogen;           /* Inode Generation Count. */
  fcl_time_t fr_time;            /* Time. */
  union fcl_vardata {
    char                    *fv_cmdname;
    struct fcl_nminfo       fv_nm;
    struct fcl_iostats      *fv_stats;
    struct fcl_evmaskinfo   fv_evmask;
} fr_var;
  uint64_t              fr_tdino;             /* Target dir ino */
  char                   *fr_newfilename;      /* For rename */
  struct fcl_acsinfo     *fr_acsinfo;          /* Access Info */
};
struct fcl_nminfo {
  uint64_tfn_pinonum;/* Parent Inode Number. */
  uint32_tfn_pinogen;/* Parent Inode Gen cnt. */
  char*fn_filename;
};
struct fcl_evmaskinfo {
  uint64_toldmask;/* Old event mask. */
  uint64_tnewmask;/* New event mask. */
};
