block: rename BIO_MAX_PAGES to BIO_MAX_VECS

2021-03-11T14:47:48Z

Ever since the addition of multipage bio_vecs BIO_MAX_PAGES has been horribly confusingly misnamed. Rename it to BIO_MAX_VECS to stop confusing users of the bio API.

treewide: Use sizeof_field() macro

2019-12-09T18:36:44Z

Replace all the occurrences of FIELD_SIZEOF() with sizeof_field() except at places where these are defined. Later patches will remove the unused definition of FIELD_SIZEOF(). This patch is generated using following script: EXCLUDE_FILES="include/linux/stddef.h|include/linux/kernel.h" git grep -l -e "\bFIELD_SIZEOF\b" | while read file; do if [[ "$file" =~ $EXCLUDE_FILES ]]; then continue fi sed -i -e 's/\bFIELD_SIZEOF\b/sizeof_field/g' $file; done Signed-off-by: Pankaj Bharadiya Link: https://lore.kernel.org/r/20190924105839.110713-3-pankaj.laxminarayan.bharadiya@intel.com Co-developed-by: Kees Cook Signed-off-by: Kees Cook Acked-by: David Miller # for net

raid5: set write hint for PPL

2019-03-12T17:15:18Z

When the Partial Parity Log is enabled, circular buffer is used to store PPL data. Each write to RAID device causes overwrite of data in this buffer so some write_hint can be set to those request to help drives handle garbage collection. This patch adds new sysfs attribute which can be used to specify which write_hint should be assigned to PPL. Acked-by: Guoqing Jiang Signed-off-by: Mariusz Dabrowski Signed-off-by: Song Liu
