π megasas_mgmt_ioctl β char node ioctl entry point π
okay so this is megasas_mgmt_ioctl(9) from the Kernel API Manual, and it's lowkey the whole vibe of the char node's ioctl entry point. bestie, it's giving "front door of the megaraid_sas driver" and honestly? iconic. β¨
πΈ NAME πΈ
megasas_mgmt_ioctl β char node ioctl entry point
like, that's it, that's the whole job description, and it ate. π
π SYNOPSIS π
long megasas_mgmt_ioctl (struct file *file , unsigned int cmd , unsigned long arg );
no cap, that's the exact signature β long in, three args, ship it. π«Ά
π¦ ARGUMENTS π¦
fileβ char device file pointer. it's literally the file you're talking to, bestie, the char device link in the group chat. πcmdβ ioctl command. the thing that tells the driver what you want. main character energy, fr. βargβ ioctl command arguments address. the address where the actual arguments are hanging out, waiting to be read. π
π SEE ALSO π
first up: the Kernel file holding all of this, ./drivers/scsi/megaraid/megaraid_sas_base.c β that's the source, go read it, it's a whole journey. π

like, that's the whole crew and they all showed up. not one flake. π₯
and that's the page, bestie! π this masterpiece lives in ./drivers/scsi/megaraid, stamped October 2026 β so when you cite it, cite it cute. slay, go read the source, mwah πβ¨
