| |
Move BCACHEFS_STATFS_MAGIC value to UAPI <linux/magic.h> under BCACHEFS_SUPER_MAGIC definition (use common approach for name) and reuse the definition in bcachefs_format.h BCACHEFS_STATFS_MAGIC.
There are other bcachefs magic definitions: BCACHE_MAGIC, BCHFS_MAGIC, which use UUID_INIT() and are used only in libbcachefs. Therefore move only BCACHEFS_STATFS_MAGIC value, which can be used outside of libbcachefs for f_type field in struct statfs in statfs() or fstatfs().
Suggested-by: Su Yue <l@damenly.org> Signed-off-by: Petr Vorel <pvorel@suse.cz> --- Changes v2->v3: * Align tab with other entries.
Changes v1->v2 (all suggested by Brian Foster - thanks!): * rename constant to BCACHEFS_SUPER_MAGIC, * keep BCACHEFS_STATFS_MAGIC in bcachefs_format.h, just include <uapi/linux/magic.h> and use BCACHEFS_SUPER_MAGIC definition, * move the constant to the first chunk.
Kind regards, Petr
