Hi, We came across what seems to be a crash consistency bug on btrfs and f2fs. When we create a symlink for a file and fsync the symlink, on recovery from crash, the fsync-ed file is missing.
You can reproduce this behaviour using this minimal workload : 1. symlink (foo, bar) 2. open bar 3. fsync bar ----crash here---- When we recover, we find that file bar is missing. This behaviour seems unexpected as the fsynced file is lost on a crash. ext4 and xfs correctly recovers file bar. This seems like a bug. If not, could you explain why? Do let me know if I am missing some detail here.
