Records the file attribute flags as of Linux program chattr(1) and
ioctl(FS_IOC_GETFLAGS) in <linux/fs.h> as bits in a byte string.
Known from Debian GNU/Linux 8 to 12 are:
bit0= FS_SECRM_FL 's' zero blocks on deletion
bit1= FS_UNRM_FL 'u' on delete prepare for undelete
bit2= FS_COMPR_FL 'c' compress
bit3= FS_SYNC_FL 'S' synchronous write
bit4= FS_IMMUTABLE_FL 'i' immutable
bit5= FS_APPEND_FL 'a' appending write only
bit6= FS_NODUMP_FL 'd' dump(8) shall ignore this file
bit7= FS_NOATIME_FL 'A' do not update atime
bit8= FS_DIRTY_FL 'Z' compressed dirty file
bit9= FS_COMPRBLK_FL (? one or more compressed clusters)
bit10= FS_NOCOMP_FL 'm' do not compress
bit11= FS_ECOMPR_FL 'E' compression error (old)
FS_ENCRYPT_FL 'E' encrypted file (new)
bit12= FS_BTREE_FL (? btree format dir)
FS_INDEX_FL 'I' hash-indexed directory ?
bit13= FS_IMAGIC_FL (? AFS directory)
bit14= FS_JOURNAL_DATA_FL 'j' data journalling
bit15= FS_NOTAIL_FL 't' no tail-merging
bit16= FS_DIRSYNC_FL 'D' synchronous directory updates
bit17= FS_TOPDIR_FL 'T' top of directory hierarchy
bit18= FS_HUGE_FILE_FL ('h' huge file ? 'h' old, FS_HUGE_FILE_FL new)
bit19= FS_EXTENT_FL 'e' using extents
bit20= FS_DIRECTIO_FL (? use direct i/o) (old)
FS_VERITY_FL 'V' fs-verity enabled (new)
bit21= FS_EA_INODE_FL (? Inode used for large EA)
bit22= FS_EOFBLOCKS_FL (? reserved for ext4)
bit23= FS_NOCOW_FL 'C' no copy on write
bit25= FS_DAX_FL 'x' direct access
bit28= FS_INLINE_DATA_FL 'N' data stored in inode
bit29= FS_PROJINHERIT_FL 'P' project hierarchy
bit30= FS_CASEFOLD_FL 'F' case-insensitive directory lookups
bit31= FS_RESERVED_FL (? reserved for ext2 lib)
Format of Value:
A byte string which begins with the most significant byte.
Example:
(FS_SECRM_FL|FS_APPEND_FL|FS_NOCOMP_FL) = 0x421
