When I search FHANDLE in menuconfig I get: |
| 44 |
|
| 45 |
│ Symbol: FHANDLE [=y] |
| 46 |
│ Type : boolean |
| 47 |
│ Prompt: open by fhandle syscalls |
| 48 |
│ Location: |
| 49 |
│ (1) -> General setup |
| 50 |
│ Defined at init/Kconfig:235 |
| 51 |
│ Selects: EXPORTFS [=y] |
| 52 |
│ Selected by: GENTOO_LINUX_INIT_SYSTEMD [=y] && GENTOO_LINUX [=y] |
| 53 |
&& GENTOO_LINUX_UDEV [=y] |
| 54 |
|
| 55 |
This clearly states that the prompt you're looking for is a line that |
| 56 |
says "open by fhandle syscalls" under "General setup" |
| 57 |
|
| 58 |
Sure, it's not the absolute simplest interface (i.e. it doesn't give a |
| 59 |
'enable this' in the search results) but it does give all the |
| 60 |
necessary information about a given option to find it (as well as |
| 61 |
dependencies and their current states, etc). The most likely reason |
| 62 |
the news item doesn't list the specific "prompt" text (or even the |
| 63 |
category) is that, across even sub release versions of the kernel |
| 64 |
those are prone to change (and, at times, drastically) while the |
| 65 |
actual CONFIG_<name> option tends to be fairly static through time |
| 66 |
once it exists (even when superseded by new toys, i.e. older |
| 67 |
IDE/ATA/ATAPI options vs newer PATA options). |
