https://bugzilla.kernel.org/show_bug.cgi?id=111891 Andreas Dilger <adilger.kernelbugzilla@xxxxxxxxx> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |adilger.kernelbugzilla@dilg | |er.ca --- Comment #1 from Andreas Dilger <adilger.kernelbugzilla@xxxxxxxxx> --- I'm not sure where you got the idea that the access time of all parent directories should be changed, but that isn't how POSIX works. Only the access time of the file will be modified, otherwise there would be a huge amount of overhead (e.g. maybe dozens of disk writes) for every file access. Also, most filesystems have no way of determining the parent directories for a given file, and there may be multiple parent directories for a single file (hard links), and it wouldn't make sense to update all of those directories, so this is also impractical to implement for most filesystems. People have enough problems with atime without making it even more expensive, and relatime is already reducing the number of cases where atime is updated significantly. Seems I cannot close this bug (Ted, can you give me permission for this?), but it should be closed as "not a bug". -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
