| Subject | [PATCH 1/2] f2fs: enable inline_xattr by default |
| Message-ID | <t8x2W-74c-11@gated-at.bofh.it> |
In android, since SElinux is enable, security policy will be appliedd for each file, it stores in inode as an xattr entry, so it will take one 4k size node block additionally for each file. Let's enable inline_xattr by default in order to save storage space.
