Subject: [RFC scripts] Modules info in one liner script

Hi Masahiro/Michal/Randy.

This is very trivial and one line script to extract out the running
kernel modules with descriptions, like below

filename:
/lib/modules/5.4.1-arch1-1ArchLinux-5.4.1/kernel/drivers/ata/libata.ko.xz
description:    Library module for ATA devices
depends:        scsi_mod
filename:
/lib/modules/5.4.1-arch1-1ArchLinux-5.4.1/kernel/drivers/usb/host/xhci-pci.ko.xz
description:    xHCI PCI Host Controller Driver
depends:        xhci-hcd
filename:
/lib/modules/5.4.1-arch1-1ArchLinux-5.4.1/kernel/drivers/usb/host/xhci-hcd.ko.xz
description:    'eXtensible' Host Controller (xHC) Driver
depends:
filename:
/lib/modules/5.4.1-arch1-1ArchLinux-5.4.1/kernel/drivers/scsi/scsi_mod.ko.xz
description:    SCSI core
depends:
filename:
/lib/modules/5.4.1-arch1-1ArchLinux-5.4.1/kernel/arch/x86/crypto/crc32c-intel.ko.xz
description:    CRC32c (Castagnoli) optimization using Intel Hardware.
depends:
filename:
/lib/modules/5.4.1-arch1-1ArchLinux-5.4.1/kernel/drivers/usb/host/ehci-pci.ko.xz
description:    EHCI PCI platform driver
depends:        ehci-hcd
filename:
/lib/modules/5.4.1-arch1-1ArchLinux-5.4.1/kernel/drivers/usb/host/ehci-hcd.ko.xz
description:    USB 2.0 'Enhanced' Host Controller (EHCI) Driver

and the code to do this :

 awk '{print $1}' "/proc/modules" | xargs modinfo | awk
 '/^(filename|desc|depends)/'

 Can we put in a script called "kernel_modules_info.sh"
 under scripts dir??

 Kindly let me know your thoughts.

 Thanks,
 Bhaskar
