core.sys.linux.fs

D header file for the linux/fs.h interface.

This file has definitions for some important file table structures and constants and structures used by various generic file system ioctl's.

fsxattr struct fsxattr: Structure for FS_IOC_FSGETXATTRA and FS_IOC_FSSETXATTR.
inodes_stat_t struct inodes_stat_t: Undocumented in source but is binding to C. You might be able to learn more by searching the web for its name.
