inotify: do not set FS_EVENT_ON_CHILD in non-dir mark mask

2020-07-27T21:16:16+00:00

FS_EVENT_ON_CHILD has currently no meaning for non-dir inode marks. In the following patches we want to use that bit to mean that mark's notification group cares about parent and name information. So stop setting FS_EVENT_ON_CHILD for non-dir marks. Link: https://lore.kernel.org/r/20200722125849.17418-3-amir73il@gmail.com Signed-off-by: Amir Goldstein Signed-off-by: Jan Kara

inotify: report both events on parent and child with single callback

2020-07-27T19:24:51+00:00

fsnotify usually calls inotify_handle_event() once for watching parent to report event with child's name and once for watching child to report event without child's name. Do the same thing with a single callback instead of two callbacks when marks iterator contains both inode and child entries.

fsnotify: pass dir argument to handle_event() callback

2020-07-27T16:32:47+00:00

The 'inode' argument to handle_event(), sometimes referred to as 'to_tell' is somewhat obsolete. It is a remnant from the times when a group could only have an inode mark associated with an event. We now pass an iter_info array to the callback, with all marks associated with an event. Most backends ignore this argument, with two exceptions: 1. dnotify uses it for sanity check that event is on directory 2. fanotify uses it to report fid of directory on directory entry modification events Remove the 'inode' argument and add a 'dir' argument. The callback function signature is deliberately changed, because the meaning of the argument has changed and the arguments have been documented. The 'dir' argument is set to when 'file_name' is specified and it is referring to the directory that the 'file_name' entry belongs to. Signed-off-by: Amir Goldstein Signed-off-by: Jan Kara

inotify: do not use objectid when comparing events

2020-07-15T15:36:58+00:00

inotify's event->wd is the object identifier. Compare that instead of the common fsnotidy event objectid, so we can get rid of the objectid field later. Link: https://lore.kernel.org/r/20200708111156.24659-6-amir73il@gmail.com Signed-off-by: Amir Goldstein Signed-off-by: Jan Kara

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21+00:00

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

fsnotify: replace inode pointer with an object id

2020-03-24T10:28:00+00:00

The event inode field is used only for comparison in queue merges and cannot be dereferenced after handle_event(), because it does not hold a refcount on the inode. Replace it with an abstract id to do the same thing. Link: https://lore.kernel.org/r/20200319151022.31456-8-amir73il@gmail.com Signed-off-by: Amir Goldstein Signed-off-by: Jan Kara
