2010-02-26mtd: blktrans: Hotplug fixesMaxim Levitsky
* Add locking where it was missing. * Don't do a get_mtd_device in blktrans_open because it would lead to a deadlock; instead do that in add_mtd_blktrans_dev. * Only free the mtd_blktrans_dev structure when the last user exits. * Flush request queue on device removal. * Track users, and call tr->release in del_mtd_blktrans_dev Due to that ->open and release aren't called more that once. Now it is safe to call del_mtd_blktrans_dev while the device is still in use. Signed-off-by: Maxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2008-12-10[MTD] update internal API to support 64-bit device sizeAdrian Hunter
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. Extending the external API is a separate issue for several reasons. First, no one needs it at the moment. Secondly, whether the implementation is done with IOCTLs, sysfs or both is still debated. Thirdly external API changes require the internal API to be accepted first. Note that although the MTD API will be able to support 64-bit device sizes, existing drivers do not and are not required to do so, although NAND base has been updated. 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 - NAND base support - 32-bit local variables used by mtdpart and mtdconcat - naughtily assuming one structure maps to another in MEMERASE ioctl Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) / (d)) but is perhaps more readable. Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

2006-11-28[MTD] [NAND] remove len/ooblen confusion.Vitaly Wool
As was discussed between Ricard Wanderlöf, David Woodhouse, Artem Bityutskiy and me, the current API for reading/writing OOB is confusing. The thing that introduces confusion is the need to specify ops.len together with ops.ooblen for reads/writes that concern only OOB not data area. So, ops.len is overloaded: when ops.datbuf != NULL it serves to specify the length of the data read, and when ops.datbuf == NULL, it serves to specify the full OOB read length. The patch inlined below is the slightly updated version of the previous patch serving the same purpose, but with the new Artem's comments taken into account. Artem, BTW, thanks a lot for your valuable input! Signed-off-by: Vitaly Wool <vwool@ru.mvista.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
