Worked on the geerlingguy/linux repository to enhance the stability of the GFS2 filesystem by addressing issues related to folio migration and exhash directory depth validation. Focused on kernel development and filesystem internals, the work involved implementing migrate_folio in both gfs2_rgrp_aops and gfs2_meta_aops using C, ensuring safe folio migration and reducing kernel warnings. Additionally, validated i_depth for exhash directories and clarified depth calculation logic with ilog2 to prevent undefined behavior. These targeted bug fixes improved reliability and reduced xfstest failures, contributing to more robust GFS2 operations in production and downstream environments while demonstrating strong debugging skills.
