Re: [PATCH 1/5] mtd: Update internal API to support 64-bit device size

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello Sascha,

eyah, I've had some problems sending mails with git send-email
through my proxy so tried to use thunderbird to pass patches outside.
Which apparently did some improvisation on them :)

Anyway, I have fixed my sendmail and will resend patches soon.

Best regards,
Lavnikevich Dmitry

MTD internal API presently uses 32-bit values to represent device
size. This patch updates them to 64-bits but leaves the external API
unchanged.

In general, changing from 32-bit to 64-bit values cause little
or no changes to the majority of the code with the following
exceptions:
   - printk message formats;
   - division and modulus of 64-bit values (mtd_div_by_wb,
     mtd_div_by_eb may be used in some of such cases).

Was tested on phyFLEX i.MX6.

Your patches look all good. Unfortunately I can't apply them because
your mailer wraps lines.

Could you try resending it using git-send-email?
