Hi all,
I couldn't access easy a rdev super block (mdp_superblock_s) by remote gdb
(exactly at the places where I wish to print it), so are there any
constraints against keep a mdp_supeblock_t * sb_rdev in mdk_rdev_s as well
as page *sb_page ? like in 2.4 kernel ? It could also make better overall
performance due to that page_address() calls would be unnecessary.
The pointer could be kmapp'ed once after the sb_page is set and kept as
long as drive is present in the array.
Regards,
Krzysztof Blaszkowski
