Note: please make sure to= read the bugs and limitations section at the end of this document. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ : : BUGS AND LIMITATIONS The =E2=80=98c=E2=80=99, =E2=80=99s=E2=80=99, and =E2=80=98u=E2= =80=99 attributes are not honored by the ext2 and ext3 ^^^ filesystems as implemented in the current mainline Linux ke= rnels. These attributes may be implemented in future versions of the ex= t2 and ext3 filesystems. I agree it is a bug that the _man_page_ doesn't also mention ext4 as NO= T zeroing out blocks when "+s" is used. It makes me wonder why these "features" are mentioned in the man page a= t all, since it never worked and there is no plan to make it work. Since this question comes up on a regular basis, it makes me wonder if it would be= better to just remove mention of these options until they are actually impleme= nted.=20 When they ARE implemented, they should list explicitly which filesystem= s DO support those features, rather than redirecting to the end of the docum= ent. --=20 Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=3Demai= l ------- 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" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
