inherit_flags(9)

💅 inherit_flags(9) 💅

okay so this is the Kernel API Manual page for inherit_flags, and bestie, it’s giving “small helper, big inheritance energy.” ✨

---

🌸 NAME 🌸

inherit_flags — inherit flags of the parent inode. periodt. 💖

✨ SYNOPSIS ✨

int inherit_flags (const struct inode *dir , umode_t mode );

🎀 ARGUMENTS 🎀

• dir — parent inode.
• mode — new inode mode flags.

🦋 DESCRIPTION 🦋

okay so inherit_flags is a helper function for ubifs_new_inode, and its whole thing is inheriting the flag of the parent directory inode dir. no cap, that’s the vibe.

UBIFS inodes inherit the following flags:

• UBIFS_COMPR_FL — useful to switch compression on/of on sub-directory basis;
• UBIFS_SYNC_FL — useful for the same reasons;
• UBIFS_DIRSYNC_FL — similar, but relevant only to directories.

and yeah, this function returns the inherited flags. that’s the whole return moment. 💅
