2020-08-23treewide: Use fallthrough pseudo-keywordGustavo A. R. Silva
Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case. [1] Signed-off-by: Gustavo A. R. Silva <>
2019-04-30block: switch all files cleared marked as GPLv2 to SPDX tagsChristoph Hellwig
All these files have some form of the usual GPLv2 boilerplate. Switch them to use SPDX tags instead. Reviewed-by: Chaitanya Kulkarni <> Signed-off-by: Christoph Hellwig <> Signed-off-by: Jens Axboe <>
2017-11-03badblocks: fix wrong return value in badblocks_set if badblocks are disabledLiu Bo
MD's rdev_set_badblocks() expects that badblocks_set() returns 1 if badblocks are disabled, otherwise, rdev_set_badblocks() will record superblock changes and return success in that case and md will fail to report an IO error which it should. This bug has existed since badblocks were introduced in commit 9e0e252a048b ("badblocks: Add core badblock management code").

2017-06-21block: Add fallthrough markers to switch statementsBart Van Assche
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 Signed-off-by: Bart Van Assche <> Signed-off-by: Jens Axboe <>
2016-10-21badblocks: badblocks_set/clear update unacked_existShaohua Li
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. Signed-off-by: Shaohua Li <> Reviewed-by: Tomasz Majchrzak <> Tested-by: Tomasz Majchrzak <> Signed-off-by: Jens Axboe <>
2016-10-12badblocks: fix overlapping check for clearingTomasz Majchrzak
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 Williams
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 <>
2016-01-09block: clarify badblocks lifetimeDan Williams
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 <>
2016-01-09badblocks: rename badblocks_free to badblocks_exitDan Williams
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 <>
2016-01-09badblocks: Add core badblock management codeVishal Verma
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.
