Hi Jiucheng, I am trying to remove FGP_NOFS from the kernel and the last remaining user was added by you last year in commit 2308de27c03d. I'm trying to understand why. Did you see an actual problem if you do not use it, or was it theoretical? The commit message says "to avoid potential deadlock issues", but it's not clear to me whether you know they are there, or only think they are there. I'd really like to understand what the issues are as the normal issues which make calling into the filesystem (holding another folio locked, holding a mutex relied upon by reclaim) don't seem to be present. So if there is something, I'm not sure what it is. _______________________________________________ Linux-f2fs-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/linux-f2fs-devel
