Superblock/ Inode-List

[Esco]

Hello,

when the free Inode-list in the superblock is empty, there will be a function how update the inode-list with free inodes. On which location does the kernel prove this requirement? The requirement is: Free Inode-List = Empty!(ext2)
Thanks for your help and sorry for my english
best regards

In case you haven't checked , there is on-line linux source code navigator

Thanks for your answer!
I checked the linux source but i can´t find the function which checks if the superblock free inode list is empty!!!

struct ext2_super_block {
374 __le32 s_inodes_count; /* Inodes count */
375 __le32 s_blocks_count; /* Blocks count */
376 __le32 s_r_blocks_count; /* Reserved blocks count */
377 __le32 s_free_blocks_count; /* Free blocks count */
378 __le32 s_free_inodes_count; /* Free inodes count */

Where is the s_free_inodes_count is check if it´s empty or not?
Thank you

I don't know the exact function where and how it was checked. I would highly recommend you to drop a mail to ext3-developers list. I'm sure you get more answers. https://www.redhat.com/mailman/listinfo/ext3-users
