2017-06-21block: Add fallthrough markers to switch statementsBart Van Assche1-0/+1
This patch suppresses gcc 7 warnings about falling through in switch statements when building with W=1. From the gcc documentation: The -Wimplicit-fallthrough=3 warning is enabled by -Wextra. See also https://gcc.gnu.org/onlinedocs/gcc-7.1.0/gcc/Warning-Options.html. Signed-off-by: Bart Van Assche <bart.vanassche@wdc.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2016-10-21badblocks: badblocks_set/clear update unacked_existShaohua Li1-0/+23
When bandblocks_set acknowledges a range or badblocks_clear a range, it's possible all badblocks are acknowledged. We should update unacked_exist if this occurs.

2016-10-12badblocks: fix overlapping check for clearingTomasz Majchrzak1-2/+4
Current bad block clear implementation assumes the range to clear overlaps with at least one bad block already stored. If given range to clear precedes first bad block in a list, the first entry is incorrectly updated. Check not only if stored block end is past clear block end but also if stored block start is before clear block end.

2016-01-09block, badblocks: introduce devm_init_badblocksDan Williams1-13/+35
Provide a devres interface for initializing a badblocks instance. The pmem driver has several scenarios where it will be beneficial to have this structure automatically freed when the device is disabled / fails probe. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2016-01-09block: clarify badblocks lifetimeDan Williams1-0/+2
The badblocks list attached to a gendisk is allocated by the driver which equates to the driver owning the lifetime of the object. Do not automatically free it in del_gendisk(). This is in preparation for expanding the use of badblocks in libnvdimm drivers and introducing devm_init_badblocks(). Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2016-01-09badblocks: rename badblocks_free to badblocks_exitDan Williams1-3/+3
For symmetry with badblocks_init() make it clear that this path only destroys incremental allocations of a badblocks instance, and does not free the badblocks instance itself. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2016-01-09badblocks: Add core badblock management codeVishal Verma1-0/+561
Take the core badblocks implementation from md, and make it generally available. This follows the same style as kernel implementations of linked lists, rb-trees etc, where you can have a structure that can be embedded anywhere, and accessor functions to manipulate the data. The only changes in this copy of the code are ones to generalize function/variable names from md-specific ones. Also add init and free functions.
