F: drivers/net/* all files in drivers/net, but not below
F: */net/* all files in "any top level directory"/net
One pattern per line. Multiple F: lines acceptable.
+ N: Files and directories with regex patterns.
+ N: [^a-z]tegra all files whose path contains the word tegra
+ One pattern per line. Multiple N: lines acceptable.
X: Files and directories that are NOT maintained, same rules as F:
Files exclusions are tested before file matches.
Can be useful for excluding a specific subdirectory, for instance:
X: net/ipv6/
matches all files in and below net excluding net/ipv6/
K: Keyword perl extended regex pattern to match content in a
- patch or file, or an affected filename. For instance:
+ patch or file. For instance:
K: of_get_profile
- matches patch or file content, or filenames, that contain
- "of_get_profile"
+ matches patches or files that contain "of_get_profile"
K: \b(printk|pr_(info|err))\b
- matches patch or file content, or filenames, that contain one or
- more of the words printk, pr_info or pr_err
+ matches patches or files that contain one or more of the words
+ printk, pr_info or pr_err
One regex pattern per line. Multiple K: lines acceptable.
