https://bugzilla.kernel.org/show_bug.cgi?id=92271 Eric Sandeen <sandeen@xxxxxxxxxx> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |sandeen@xxxxxxxxxx --- Comment #6 from Eric Sandeen <sandeen@xxxxxxxxxx> --- As long as you don't truncate the file first, overwriting an existing ext4 file will indeed overwrite the existing blocks allocated to that file. Ext4 is not a copy on write filesystem. FWIW, recent kernels and recent util-linux also have "fstrim --secure" to issue a secure discard post-deletion. -Eric -- 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
